Guys, I've got two sets of rocker trim, one set is smooth, one set has a ridge in it. Which set is early 64? Which is late. I'm sorting through piles of parts trying to get the right stuff. My car was born in 3rd week in June in Baltimore 64 Lemans convert.

Which set should I be using. Or is the flat stuff something totally not even Pontiac. I'm trying to order clips and it seems there is an early and late style trim and clip.

Thanks Dean

This pic may be way to small to see. I've been fighting to resize it.

2 on left are the only style i have ever seen .

Same for me.

#1 could be 66. I'd have to see the other end (your pic shows the back end)
#2 is 64-5
#3 and 4 appear to be '67 Lemans/Tempest, but could be later model. Can' tell without knowing the length.
I have about 8 sets of '64-5 and they are all the same.

The two on the left are the same and two on the right are the same. The two on the right may be 66 or early 64, one of them has a long rusty flat bracket/clip about 10-12 inches long in the center similar to the hardware kits for 66-67. So I guess the 2 on the right are 66.

Here's a pic from the PY catalog, showing early/late clips. That's what confused me. So I guess I need the late clips to use the 2 moldings on the left.

Thanks for the help. I wonder what the early 64 moldings look like?

Andre, I agree those could be 67 lemans/tempest. My Dad parted out a lot of those in the 80's, he may have just put those in the pile of parts for this 64 that we kept. All four are really close to the same length. #1 and #2 are the same (I hope one L and one R) I'll have to check tonight.

Thanks again.

I have a Nov '63 built '64 GTO from Fremont.

AFAIK, the moldings were same all model year long.

The only difference is the clips and possibly the holes in the body for the clips.

IIRC, my car needs the late style clips based on the holes in my body.

I discussed this a few months back with another member here by email.

Here is what I wrote then about mine:

I have 2 ROUND holes for mounting each clip.

They are 1-1/2" center to center, vertical.

The lower hole is 5/16" dia.

The upper hole is probably a screw hole, about 1/8" dia.

The Parts Book isn't any real help.

The Vendors show an early '64 Type Clip and a 2nd style late '64 Type Clip.

Since my car is relatively early, I kinda expected to need the early clips, but they mount without screws. And I couldn't figure out if my top holes work with that style or were screw holes.

The ones the vendors call the late '64 style look to use round holes.

They mount with screws but I didn't know what size, so still wasn't sure if my 1/8" dia. top holes are okay for the screws.

In the PY Catalog, it looks in the tiny picture that the retainer clip mounting screws ARE bigger than the finish screws used at the ends of the molding (the screws that are exposed and can be seen when the molding is mounted).

That looks to match the holes on my body and fender, the end holes seem smaller in dia. than the top holes for the hidden clips.

The Parts Book does NOT show an early and late '64 Retainer Clip.

They list p/n 9774531 for the Retainer which seems like an early enough p/n for '64 application. A bit confusing since they say 10 per car in '64 (but 12 of same for '65) and my car is definitely set up for 12 Retainers. Possibly only (10) used for the '64 big cars or else (10) was a mistake.

They also list a Clip Package under p/n 9777047, 2 Packages per car needed. That is a late '64 p/n but possibly just means they include (6) Retainers in each Package (and possibly all the screws too). Various Package p/ns were released late year for Service use, so this Package probably for that purpose and not an indication of a late retainer design change.

The front & rear molding to fender & body finish screws are listed as p/n 187605 and described as No. 8-15 x 3/4". This screw was Stainless Steel, Oval Head.

The Retainer mounting screws were p/n 9420755. This screw is listed as a No. 10-20 x 1/2". This one was Phosphate coated carbon steel, Hex Head. The Hex Head isn't just hex with flat top, it has some sort of recess in the top perhaps for an allen head bit in the head as well. The illustration in the Parts Book for the Hex head screws isn't conclusive.

I haven't pursued it any further.

I agree with everybody else, ones on the right aren't '64. Whether the ones on the left are a matched '64 set, you'll have to figure out.

Check the holes in your body. That will tell you if you need early or late clips.

If mine used late clips, that would suggest the change in clip style was done pretty early in the model year.

See if your holes match to the ones I described on my car.

If anybody has a car that used the early clips, I'd be interested in learning what the mounting holes in the body look like.
