My 70 350 Skylark has the pegleg 2:73 rear end. I don't mind the gear ratio so much, but the single squealing tire is annoying. Sooo, what can I do here? I think a 70 posi carrier assembly is out of the question due to availability. Is there a complete third member assembly that can essentially be swapped in place of the exsisting unit? A rear gear that I would LOVE would be the 3:23, but I won't hold my breath for that. I am looking for simplicity here guys. The car is never going to need high perfomance (high HP) rear end parts. The 350 will never get above 300 HP at the flywheel I imagine. Suggestions? Advice?
Air bag? I put air bags on my 70GS455 with a single trac 2:93. With 12lbs. in the right and 5lbs in the left it would spin both tires most of the time but not always. Good Luck Bert
2.73 and up carriers are readily available at Summit. And the gear set you want. You'll need an install kit too. Comes with everything you need.
Crap I thought it was an 8.5. I put a 12-bolt Chevy in mine and had no trouble at all. Driveshaft and control arms bolted right up. But then I promptly blew it up. LOL!! ou: New Moser c-clip eliminators ,axles and a new Strange carrier later it's bullet proof.. I hope. :TU: Is the 8.5 different than the 8.2 dimensions? I didn't think you needed to shorten the driveshaft. I didn't when going to the 12 bolt. Then again the 12-bolt was standard in the Canada cars. o No: I see they sell a carrier for a 8.2 but you need a bank loan. :laugh:
Another thing I noticed is that the 12-bolt parts are cheaper than the 8.5 10 bolt stuff. That would be the way to go if you wanted a new rear. :TU:
Thanks guys. I have no loyalty to the 8.2 and the availability of 8.5 stuff is plentiful to say the least. Shortening the drive shaft? How much do you shorten it? Cost? A direct bolt in is nice! I do not want to go above 3:23 though, my GS is 3:42 and it is reving pretty good at freeway speeds. I like the low RPM cruising of the Lark sometimes, know what I mean?
Woo hoo! :TU: This is good news. Now I know what to start looking for...eventually. I MUST not go crazy with this project or I won't be drving her this summer, and I want to drive her!
I have a correct coded 1970,8.2,with a 3.42 posi rear that I'd sell for $1200.00 NO less. I want to upgrade to a 8.5 and thats what it will cost me to do what I need to do to make it bulletproof...
Posi rear end I have a 12 bolt chevy posi rear end out of a chevelle for sale. It needs set up, drum to drum w/ 3 axles,NIB 4.11 Richmond gears. I'll take $275.00 for it. It's from a 69 chevy chevelle. Jeff Owens: Stagedskylark- ASTROCRAZY@sbcglobal.net 937-859-4790 West Carrollton,Oh 45449
o No: o No: o No: A well built HD posi 12 bolt A-body r/e that is just as strong as HD posi 30 spline 8.5 A-body rearend will run well over $1700. Same strength HD posi 8.5 A-body rear can be bought outright for $1350. Got Posi? :3gears: Roger
Ya know, I got on the Jegs website and they have an Auburn unit that is supposed to fit an BOP 8.2. Hmm. But will it really??? What about a ring and pinion though? I do not want a low gear. 3:42 is too much. A 3:08 or 3:23 is what I would like. Again, this is a cruising car and a screaming engine at 70 MPH is not desired. Everyone wants 3:73's these days. My 93 notchback stang had 3:55's, while everyone else had 3:73 or 4:11 gears. Yep they were fun, but I usually spanked them because of their endless tire spin on the street. Not to mention I could be quick and fast, not just quick. Anyways (don't know why I went there) I will keep the open gear before I switch to a low gear. The Chevelle axle assembly looks most promising, but continue to chime in guys. :beer
Hey Jeff and Bignasty, thanks for the offers, but I will pass at this point. I'm sure I will kick myself later... Does anyone have exactly what I want? An 71- 72 8.5 complete assembly (with or without the gears I want 'cause I will need no higher than 3:23 max) and poss a driveshaft? I really want to just bolt the stuff in my Lark with minimal fabrication and repairs. Call me lazy, but I gotta ask. Let me know. Again, thanks for the input as usual. :TU: BTW, if you are really far away from me, shipping could be an issue. I can pick it up within a couple hundred miles or so though. o No:
