Rear alignment questions.
I don't know a whole lot on the history of my 73 vette and I am in need of an alignment. Is the rear alligned in the same manor on all c3 vettes? Are any of these parts interchangable with older year models from c2 era? I ask this question because the rear end code shows to be a 3.55 rear end from a 65 vette. If the parts could be from an older vette, would the adjustments be the same for rear alignment ?

All suspension parts from 65-74 are all the same. Same u-joints, 1/2shafts, strut rods, rear end, t-arms. You should use alignment specs from your 73 and you'll be OK.

.....however, the Big Block cars use bigger 1/2 shafts but that doesn't affect the alignment.
The alignment for toe-in is on the front of the trailing arms where you add or take out shims. That is the main cause of tire wear and poor tracking. :chevy

Re: Rear alignment questions. (verskel)
I could of said 63-82 but I probably would have been corrected my many. 63-82 do pretty much have everything the same. Only 63-64 have drum brakes. 65-74 ALL have 2 1/2" 1/2shafts. 75-79 use 3" shafts. BB did not come any different. GM actually put larger diameter shafts on when BB stopped coming in vettes. 80-82 use different strut rods & 1/2 shafts. the 80-82 1/2 shafts have no flange and they are shorter.

Re: Rear alignment questions. (Van Steel)
Thanx for the info. I was loved enough to be given a lifetime 4 wheel alignment warantee for the vette on my birthday. I took it in for a current brake issue & an alignment, the guy says they were able to do the front but the back is not adjustable...I knew that was wrong, because of threads that I have read here in the past. the saving grace was that it was done on a computer system. it has only been pulling to the right just a little & the tread wear is pretty much normal. I will get my brake problem done with them & leave, call different stores & find out which store has a tech that knows about adjusting the rear & take it to him.

Stay away from that shop. That fellow is spouting nonsense. The toe-in is adjusted by these shims at the trailing arm bolt attachment points.
And you can see the strut rod (one of two) in this pic that is used to adjust camber.

Re: Rear alignment questions. (paul67)
I picked up the vete this afternoon. It turns out that the guy I worked with over the weekend just didn't know. The mech that is there during the week HAS done work on vettes AND KNOWS that the rear end is adjustable & how to do it. He pointed out that at this time an alignment woud do me virtually no good because all of the control arm bushings need to be replaced. Plus this mech, an older guy says that he was into rebuilding muscle cars & back in 73-74 worked for GM in Chicago. (don't know if all that is BS, but who knows, maybe I have found a good mech).
