71-72 shakers
I have five 71-72 THICK shakers in my possession right now, one 70-72 "NOS/Service Replacement" and one 73
All the 71-72 Born on car shakers have on the inside of the Fiberglass BARNUM BROS FIBRE CO INC P 481689 They have a door hinge frame glued in the rear opening The steel riveted on part has a distinct step all the way around the outside border as well as the hold down wings stamped as one piece. This is the part that is hardest to find and all attempts need to be made to save these as they are distinct to REAL born on 70-72 shakers. Part# on born on unit http://i114.photobucket.com/albums/n...ps52a695e3.jpg bottom of ear on born on http://i114.photobucket.com/albums/n...psd8aa2101.jpg step on born on http://i114.photobucket.com/albums/n...pscf06184d.jpg The 1970-72 NOS/ Service Replacement and the 73 have on the inside you can also readily see that the numbers were changed from 481689 to 491982 in a crude manner. BARNUM BROS FIBRE CO INC P 491982 This tells me that after the 1st design 70-72 steel riveted parts were used up they converted the 73-76 steel by spot welding the mounting ears on in order to hold the unit onto the 70-72 air breather base that's why there are NOS units out there that won't fit the base tabs and also spot welding on the same solenoid bracket that was used on the 70-72. They also used the 73-76 fiberglass by glueing in a 70-72 door frame instead of the frame for the block off. spot welded on ear http://i114.photobucket.com/albums/n...ps922f9b08.jpg http://i114.photobucket.com/albums/n...ps683bc3e4.jpg http://i114.photobucket.com/albums/n...psd22f3190.jpg chopped away so they could spot weld the ear onhttp://i114.photobucket.com/albums/n...ps01fe3421.jpg 73-76 lip http://i114.photobucket.com/albums/n...psd4e4f562.jpg changed part number http://i114.photobucket.com/albums/n...pscb1463e3.jpg Of course I can't tell you when Pontiac ran out of the REAL parts and started modifying later parts to work as replacements but that is what they did. So when you say NOS it may not mean DESIRABLE as it very well may be and is most likely different than a born on unit. So as shakers go Steve's has the CORRECT born on steel and believe me this is the hardest part to find in good shape. I am seeing more and more of these in very bad and rusty shape and most need major repair. So much so that I have repoped the rear sheet metal as its easier to replace it than try to fix it. Steve's is actually in my eyes more desirable than a NOS/Service Replacement unit. JMHO this is what I see on most. I fabbed a new part for this one to save it http://i114.photobucket.com/albums/n...ps8edc33b3.jpg http://i114.photobucket.com/albums/n...ps2822ef09.jpg http://i114.photobucket.com/albums/n...ps39867c25.jpg http://i114.photobucket.com/albums/n...pscb81edb0.jpg http://i114.photobucket.com/albums/n...ps6911cad2.jpg http://i114.photobucket.com/albums/n...ps3ed84c09.jpg http://i114.photobucket.com/albums/n...ps8edc33b3.jpg http://i114.photobucket.com/albums/n...ps49634145.jpg http://i114.photobucket.com/albums/n...ps69767d7a.jpg http://i114.photobucket.com/albums/n...ps9c3ecf38.jpg http://i114.photobucket.com/albums/n...ps023535f2.jpg |
No wonder you were busy last night. Probably took down many blue mountains to compose yourself....

Good info! Thanks. Do you have your own spot welder machine?

Here's one that was on ebay. It has the welded on later ears.

shake it up
I have owned 2 N.O.S. SR shaker scoops in my life...one is currently planned to go on my car...the welded on taps line up fine, so did my other in 1979, although I have seen ones that dont...it is a GM part and it works for me...as far as I am concerned NJSTEVES shaker is comparable to an original installed shaker...it features the original metal base plate...and everything is O.E.M...if you are atleast 50 years old, all of this should make perfect sense...if you did not live through the era, this is where the misunderstandings come along I think...this is where the hobby gets weird to me, but since I have lived through it, I can laugh...if someone needs an inexpensive functional shaker they do make a repop for $300

While it is nice of you Norwood to take the time to provide information, most of which is well documented if you do your research, it's obvious to me and many others that the forsale thread was not about whether or not NJSteve made a nice copy, because it obviously is. I think the gripe for most came from the original post as being described at first as an original restored 71-72 piece and it wasn't actually disclosed as a couple of scoops that have been put together from different sources (albiet correct) until someone else brought that to light in the first couple of posts.
That's where the descrepency became apparent for other people. I believe if NJSteve would have just come out and explained that in the add without 80 pages of links to read through then none of this would have started to begin with. No one is arguing that this one forsale from NJSteve isn't correctly done. So I personally don't see the point in all this. Obviously it's really bothering some of you guys and you seem hell bent on pushing the issue about correctness, LOL we all clearly get that part of it. Some good info here though for others, thanks for taking the time. |
Mr Jones, You are WELCOME......

Just curious on availability (reproduction) of the plastic insert that hinges to the trap door...?
Is something available yet or are we reworking the 73-76 insert? |

The hinge frame is a completely different part than the rivet plate frame. I saw a hinge/door assembly on ebay about 10 years ago but never saved the photos. It looked like it had never been installed so maybe it was a service part?

Guess I should have bought some? |

The problem seems to be that I assumed that everyone had the same basic knowledge of these component parts and their interchangeability between years. Thankfully Norwood is presenting the facts for them, now. But be that as it may, I have learned my lesson and will be happy to request that the moderators remove the my offending restoration thread(s) if that's what the majority of people want. |
72 T/A restoration thread
actually please do not remove that thread...it contains a lot of technical information that would be lost...I credit that thread for getting me back into my restoration over a year a go...somehow I stumbled on to it and that's what makes PY a different company than the rest..it was the T.C.S. thing that did it for me...I am not a car show person and thanks to the web and that thread...that kind of stuff is not in the service manual...especially over this shaker...now we have a thread about the different shakers, I wont even mention the 1974 G.T.O. functional shaker

If you ever get to meet these guys (Steve and Craig et al) you will see they have real Pontiac passion! Plus they make cool stuff too! Lucky to these guys post here!!

The door frame would be an easy out of steel. from the outside it would look identical to oem but it would have a slightly different look from the inside. There is that conversion kit out there but you cannot hang an original door on it, but maybe it could be modified.

You could sell it three ways....frame,door or pre-hung combination... So.....if you have 5 shakers...does that make you a hoarder? :D |
Hostage Shaker....

So let me ask the obvious question here....since SR, even if they are NOS, seem to have no value. (Now I'm not trying to be a jerk here, but really if you think about it, Norwood is right. They don't fit or look right. Ergo, no resto value as is.)
How much will it cost to make my two SR shakers correct for the 71-72 air cleaner??? One is NOS and one is fresh painted blue. May as well get them as correct as possible. Fortunately I do have a correct "born-on" piece on the car now. I'd take that off and hold it, should I resto the car, and put a "corrected" SR on the car for now. Guess I'm a hoarder too....Have more 69-71 GP manual trans console plates than he has shakers... |
