Hey guys, I'm looking for a posi 3.42 (or possibly something close) disc rear end for my 91 Trans Am. Somewhere around the central Connecticut area would be nice. I'm on a tight budget just letting you know. I'm not expecting a perfectly clean unit, but something that works. Thanks!

EDIT: I'm willing to travel a bit further if the price is right.

 

I have a 4th gen 3:23 posi rear complete with disc brakes, wider than a 3rd gen rear but works great with 4th gen or vette wheels. $250 complete NY zip 12538 not far from CT.

 

Thanks but I was really hoping for a 3.42. I don't want a 4th gen rear end because I want to keep my stock rims and I don't think that they'll look good when sticking out further. But thanks for responding!

 

3:45 9-bolt disc $300

 

Hey TPI! I was actually gonna send you a PM but you beat me to it lol. 3:45? Didn't know they had those but I guess that works. Got any pictures? And its a posi right?

 

no pics..tight came out of a 1988 formula 5-speed with 76k on it

 

Can I offer you 200 for it

Edit: And I'm looking for a front and rear disc proportioning valve to go with the drum-to-disc conversion...

 

you can but you'll only get a 3:27 for that price..can't let the 3:45 go for that

 

I have the Australian 9 bolt Limited slip with 3:23 there not posi..
[posi is full time and would eat up your tires] in NY name your price
I have the disk setup.. but you would need to get the mounting plate that bolts on the diff...I used it with my 4th Gen diff

 

How about 240 for the 3:45

 

No thank you, posi only. I don't want an open diff.

 

its a limited slip>>>> all ver 9, 10, 12 bolt [except open diffs]
everybody calls them POSI [ but the fact is they are limited slip ]
witch means it burns posi till you lets say have 1 side on the grass and 1 side on pavement
the Diff I have is what you are looking for except I do not have 3:45
it's NOT A OPEN diff 1 wheel burn
going once going twice

 

I'll keep the 3:45..but you can have a 3:27 I have for $200...in an automatic you realy don't want a 3:42
