63 super duty wheel size?
 

63 super duty wheel size? Hello fellow tempest fans. I’m trying to figure out what back wheel is on the back of the stand long super duty “eBay tempest”. I am trying to find any information from the Internet and it’s very Limited to what is on the car or what the guys would do when they converted to the rear 9.3 axle. Unfortunately I’m not going with the 9.3 I will be using a 9 inch and I have options for lug bolt pattern. I’m not sure if they used 5/ 4.75 like the small GM also the rim width and backspacing. Or even if somebody has a link to a pair of wheels for sale I would greatly appreciate anybody’s help thank you very much.

The converted differential cars used the 5X5 big car pattern

I also have a 9 inch ford rear in my 63. I bought 15×8 rims from summit.

Love the lettering. Cool car!

I'm filing all this away for when/if I do this to my '63. I'd love to see pictures of the differential installations that any of you would care to share. Thank you!

TA-69. Thank you for the reply. did you run the GM bolt pattern 5X5 or 5x4.75? Or Ford bolt pattern which is smaller. the Ford used 5 on 4.5? I like the way that we all looks I have to call Mosher they want to know where to drill the axles or if you have a part number? I would like to check the backspacing. Thank you again and yes you’re car looks awesome. Sorry if I’m being a pain in the....

I originally used a 12 bolt out of an “A” body and then decided I didn’t like the look of it. I decided to go with a 9 inch because 9.3 is very difficult to select gears / carriers. we all know the 9 inches a little more versatile for parts I have a 9.3 in my 62 and I’ve done extensive work to it to make it stronger. The 63 has a triangulated four bar.

.No I did the Gm 4.75.. Rims are summit part number 62-5834044. 4.25 back space

tekuhn, heres a pic of my rear suspension. Caltracs with there shocks and split monoleaf springs. Narrowed 69 firebird gas tank.

Thank you!

I have an A-body 12-bolt I originally built to install in my '70 Judge, but recently sold the car, so it is what I'd like to use. It looks like you used the built-in ears on the diff housing for the upper arm attachment? Triangulated 4-link with coil-overs appeals to me for the adjustability - especially ride height. Leaf springs appeal to me since it looks like it might be easier overall on the fabrication. Did you narrow the rear?

I used the tanks Inc. “A” body fuel tank. I had to make strap brackets under the trunk Now it has the same style for the A body it fits really good between the frame rails. The triangulated four bars are all double adjustable HAIM joints ends from TRZ. I used The “G” body arms because Those are little shorter and they fit really nice. Yes I did narrowed it probably 2 inches. I could go back in my history and see what the actual measurements are. If I were to do this all over again I think I also would go leafspring or maybe even Truck arm. I ordered the 62 series wheel with the 4 1/4 backspacing. BIG thank you for info...I also had to 12 Bolt A Body rear as for reason why I went with the triangulated four bar.

Here are the measurements if you want to compare thank you your 12bolt.

I took all my measurements from the mounting flange where the backing plate bolts up to the differential just about underneath the wheel cylinders.

I also cut the wheel wells and move them in probably about 1/2-3/4” inch up to the frame rail sort of the way the super duties got their modifications to fit the tire.

Anybody interested in buying a 12 bolt out of a Chevelle with 4:10 cut down maybe 2”?
