I'm helping a friend of mine get his truck on the road. He recently got a nice set of wheels and tires from my sister when she changed hers out. His truck is a '56 ford F-100, but has a mopar rear axle and we were told a camaro front clip... Wheels were dual pattern so no big deal.. Well the front clip has 5x5 bolt pattern, so the wheels won't fit now. I don't know what the clip is from. Once we figure out what the clip is, I guess we'll see if there are any hub/rotors that we can use to make it 4 3/4 bolt pattern, then if that fails, I guess we'll get other wheels. Here are some pictures, maybe someone can identify it.
dodge dakota maybe? i'd have guessed camaro, too...but i've never seen 5x5 rotors for a camaro. take that stamped number on the upper control arm in the pic and google it (should have an "R" or "L" following a string of numbers stamped on each)...if you can confirm its all camaro then maybe they swapped rotors somehow, who knows. if they did, then camaro rotors are pretty cheap to put it all back.
full size GM car 71-76, and some later ones (cop cars and wagons mostly?) used the 5 on 5 pattern, and look pretty much like a 70s camaro clip.
Camaro frames go straight back and down at the firewall area, while the midsize and and full size car frames go down and out to the sides at the same area. although it looks like there isn't enough of the subframe on this truck to be able to tell?
thanks for the info...did not know that im almost certain its as youve described re: GM fullsize...i know my 2nd gen camaro sub did NOT bow OUTWARD then down towards the firewal like this one does in the pic.
but they have the steering box and idler arm mounted to the outside of the frame, and the suspension crossmember bolts to the frame, it's not all one piece like this one.
3963994 Here's the number on the spindle. Only found one reference on google. It mentioned it being a '76 cadillac and then someone mentioned a nova is the same.. any have any more definite info on this part? Upper control arm is B2435R Dust shield was 2695L Disc was 3963996 or 3963986.. I think
Hard to see in the pictures but it looks kinda like the 96 Caprice I have in the ElCamino. it started out 5 X 5 pattern too. Swing by on Tue and you can take a look.
1973-76 Buick is what the pitman arm says..but that is on a buick site so it may be 73-76 for all GM. I tried to find the casting number on the steering box, but can't see it. Did find a broken dipstick though.. The steering box is way up front.. There's not enough of the back half of this clip to determine anything from it.
If it is a Caprice clip, you may still get away with running Camaro rotors. It is a popular swap for second gen Camaros to use the big car spindles with 3rd gen "LT1" brakes to get 12" rotors over the standard 11" Camaro rotors-and still have th 4.75" bolt pattern. You should have no problems doing the same swap. You just need the '91-'92 LT1 rotors-I think that's what they're called.
So far it looks like it is 71-76 like squirrel said.. are there rotors with 4 3/4 BP that will fit these spindles? I've ruled out 1st and 2nd gen camaro, nova cause of the front steering.. so what does that leave? fullsize?
70- up camaros are front steer. 75-79 novas and sevilles are front steer. You could probably put the 11" brakes with 4-3/4" bolt pattern on it by changing the spindles, using the 70s camaro parts
76 caddy seville is 5 on 4 3/4. 77 up seville is 5 on 5. sub frame is a lot like camaro/nova. also you can use impalla parts on a camaro sub. any way its gm.
Have to disagree with 77 up being 5 on 5. I used early 80's Seville rotors and bracketry to convert my Nova rear to disc and the bolt pattern is 5 on 4 3/4
early 80s seville is fwd, completely different car than the 77-79 but maybe you got the year wrong, because early 80s sevilles don't have a rearend?
I wasn't claiming that the frt clip here was an 80's Seville, I know they are front wheel drive. What I pointed out was that 77 up ( at least the frt whl drv) wasn't 5 on 5 pattern
early 80,s seville,s are front wheel drive and have very little in common with the 76-77 which are really built from novas i stand by the 77 being 5on5
the sub is a bit wider on the seville compared to a camaro, at least the 76 i had laying here was. had 'em sitting side by side. cut the ******* up i did.... btw, the bolt circle was 4 3/4" and i DO have the brake setup w/spindles................cheap.
FWIW, here's the history of fullsize chevy and bolt patterns. As Squirrel noted, 5x5 for the thru 76 boats, they all have 12" brakes I think. When they downsized for 77, cars with standard suspension got 11" brakes and 4.75 pattern. HD suspension had 12" brakes and 5x5. Sometime in around 90 (early in the bubble style cars) they went back to 5x5 exclusively but kept using 11" brakes standard, 12" HD Point being, if it is B body, then parts exist to change bolt pattern and use smaller brakes without customization. You may have to change one or both the A arms (get em with the spindles), because the smaller brakes use smaller balljoints. Regarding camaro spindles on a B body. They're gonna be shorter and screw with the roll center in a bad way. good luck
didn't GM also change angles of the ball joint "pin" or whatever you'd call it in '77? If that's true, will the 77 and up balljoints fit in the 76 and earlier control arms?
i guarentee you a 76 seville is 5 on 4 3/4 and a 77 is 5 on 5. i owned a 76 and used a camaro rear to change the gears out. around this time while building a late model with a camaro stub we used impalla suspenion parts to get the larger rotors and get the 5 on 5 stock car standard wheel pattern.
