Help from GM Owners
 
So, I may need some help from you that may have had or still has a Chevy before. The 41 Chrysler Street rod needs a front end rebuild.

I contacted the guy that built it, and he said he made it with the front suspension of a 70 Monte Carlo, I never believed that as its way too narrow.

I called him the other day and he said it may be 69 Nova, can any of you guys help?

I googled the part number of the Pitman arm pictured and it comes up as a 68-69 Chevelle/Firebird/Camaro, so possibly a Nova too,

I tried the caliper pictured but it didn't come up as anything, do the pictures look familiar to anyone?

I also tried posting on a few Nova websites

First, it's definitely NOT a 69 Nova. The 1968-74 Nova (and 67-69 Camaro/Firebird) were rear steer cars with the steering linkage behind the crossmember. If the spindles use bolt-on steering arms and the steering linkage is in front of the crossmember, then it's almost certainly a 1964-72 A-body clip. That includes the 70-72 Monte, in case you were wondering. Note that the 64-67 A-body suspension was about 1.5" narrower than the 68-72 cars. The good news for you is that most of the rebuild parts (ball joints and bushings) are the same between the A-body and the Camaro/Nova cars. The center links are definitely different and you should match your old one up with the replacement.

joe_padavano 05-14-2013 12:50 PM

In looking at your photos a little more, it appears that you may have aftermarket lowering spindles. The aftermarket spindles are one-piece with integral steering arms and caliper mounts, unlike the OEM spindles with bolt on steering arms and caliper mounts. The caliper looks like the generic single-piston GM caliper.

The other option is that this is a second gen 70-81 Camaro/75-79 Nova front end. Those used front steer and one-piece spindles. Unfortunately, the ball joints for those are different than on the earlier cars.

here is the 1970 chevelle frame dimensions, same frame only the monte would've been longer..

but the width at the front, should tell you if it's a 68-72 g.m. a body frame or not..

Chevelle Frames

gearheadslife 05-14-2013 03:28 PM

and here is a 1976 camaro frame
that cover 70-81 f body and 75 up nova, around 75-76 they changed the frame mounting points a little but the demensions you'd need to see if this is what you have would not have changed..

this is not a 68-72 A body.
nor a nova,
nor a camaro.
i would guess its a metric monte clip.

the reason i say its not either of these is for the fact that the frame drops significantly after the rear lower control arm mount. yours does not.

are the bolts standard or metric?

i vote X body. even tho your pitman arm says different, i would not go off 1 part that may be interchangable.

in that case it could be an s-10 frame..

Interesting. It's too wide for an S-10, the shape at the front of the crossmember is not the same as a Chevelle (64-67 or 68-72), or Malibu (78-88). The spindle (pic #9) is factory, with it's spindle position and date-time casing number system, and looks like the tall style used in '70-up F, '73-up A and '75-up X cars. Only the '73-77 Chevelle used that spindle and those are definitely too wide. The frame on A-bodies (Chevelle etc.) curves outward pretty quickly after the crossmember, this does not.

Therefore I'm saying '70-up Camaro or '75-up Nova (or associated F- or X-bodies), with their straight-shot rearward after the front cross, it appears from the pics that is where the blending between the two frames was done. That width also looks about right to me.

I don't have one handy to compare, but that's where I'd look.

Edit: Since I helped, can I tease you about the blue paint? ;)

rp23g7 05-15-2013 11:24 AM

Thanks everyone, still investigating, I haven't got under it again to check if its metric or standard, but I measured width of track and length.

its about 122 inches from center of the rear axle to front spindle center, and about 5 feet from center track to center track of the other wheel

V8&4spd 05-15-2013 12:49 PM

They look like tall spindles. Who knows what people do to make things work. Maybe they flipped the spindles upside down. There are part numbers on them, that will tell you what they are. There should be date codes on the calipers and maybe the spindles. Measure the rotors, tall spindles should be 11 inch. The 78 and up Monte Carlo rotors are 10.5 inch.

kso 05-15-2013 01:09 PM

Wheelbase unimportant if it's a blended-together frame, and track as stated is affected by wheel width/backspace. The most pertinent dimension would be, sitting at ride height with the lower a-arms parallel to the ground or nearly so, measure between the lower ball-joint centers.

Under same conditions with the wheels off (weight supported at the ball joints) you could also measure between the mounting surfaces on the discs, you would need to use a square or plumb-bob and make marks on the floor. If you go with that method (a little less precise) your width if it's a '70-'81 Camaro/Firebird (F-body), or '75-'79 Nova/Skylark/Seville etc. (X-body) should be about 63 1/2", but it's similar on the '68-'72 A's.

Really the most obvious peculiar feature of your frame is the details of the nub that sticks out from the bottom center of the crossmember, it's notably different among the various GM models...some are bigger, some little, some welded-on. You could just visually check that against the ones mentioned.

rp23g7 05-17-2013 11:35 AM

thanks for everyones help, I got under and took some measurments and part numbers.







so here are some measurments and numbers.

Calipers have two hex hold downs, 3/8 hex, the
left caliper has P/N 18002328 with a 28 8L on it and a G286 on it

right has the same number

the rotor has

337226 with a 866 and a GM 68 on it

Lower Control Arm measurments

from center ball joint to the rear attach mount is 16 inches, the front mount to the ball joint is 18 inches

Upper Control arm rear bolt to upper ball joint is 12 inches

the center link is 17,5 from center of Pitman Arm to inner tie rod and 23 inches to the idler arm.

Frame is 26 inches wide at the front, its been cut so don't know if it gets wider in a area that's further forward

the Cross member has the lower control arm mounts 15 inches apart.

the spindles have 371676 13 and a 211 on them

the bleeder on the caliper is 3/8, the castle nuts on the ball joints are 3/4 and 7/8th and the upper CA bushing has 9/16ths

.

Search is your friend. From a post on this forum in 2006:

So, the front clip is from a second gen F-body (1970-81 Camaro/Firebird).

not so fast..
many 2nd gen spindles where put in a bodys, with HO'S ball joints, before the aftermarket came around with tube a arms..
but if he uses the diagrames I posted and measures points of the frame that are different (a body/f body front clip) he'll know fer sure

V8&4spd 05-17-2013 02:25 PM

They are tall spindles. The date on them would make them 1976. GM used them on other cars also, not just Camaro. The control arms could be from something else. Tall spindles are plentifull, someone might have used them because that is what they had to work with.
