rear end question

Ive read the rear end differences sticky and Im still a bit confused.. I have a 67 lesabre with a 340/4 how do I tell what rear end it is? Also Im looking at a 70 b body posi carrier for sale how do I tell what rear end that is for so I know if it will work with my car?

thanks!

 

Looking forward to input from others as well.

What I do know is that '67 LeSabre did not use the bigger 9-3/8" carrier design used by Wildcat/Electra/Riviera that year. It may be the early Buick 8.2", I don't know, sorry.

would a 4 door wildcat have the 9 3/8?

 

From '67 and up, yes. I don't know if the housing is an easy bolt-in to a '67 LeSabre, though (if that's why you're asking).

hmmm well there goes that idea lol..... is my 8.2 the same as the 68-72 rear? if so TA sells a posi AND gears!

 

That I don't know, Jordan. Time for an expert! Send a private message with your questions to v8Buick member "monzaz". If he doesn't know, nobody does.

thanks!

 

Should be the early 8.2 rear similar to the Skylarks..... but in the carrier only. The housing is different.
Axle bearings are unique to 66-68 GS, Sportwagon, and LeSabre.....
I'll bet a 64-67 posi carrier will work for you. Monzaz will have a great price, so contact him.:TU:

 

ok now what about sway bars? same as the 67 impala????

 

Yes the 68-70 are the same as the LeSabre...1967...Humm maybe the same as the 8.2 Buick Skylark too. Got some pictures? Jim

Sway Bars - I do not think Impala had a sway bar as they were track bars on that rear. All the way to 1970 .

 

Ill take some tomorrow and post em up!
thanks.

 

No-- 8.2 rears were not the same 68-72.

 

were the carriers the same tho? Ill be uploading pics of the rear end tonight
thanks!!

 

Buick parts book shows the LeSabre as a 5000 series. Wildcat is a 6000 series which uses a different rear.
67 LeSabre uses the same center section as the 64-67 Skylarks. 68-up is different.

 

So what would that carrier be called? Its just an early 8.2? I think they make posi and gears for those!

 

what car did that posi rearend come out of?

 

It's the original rear that's still under my 67 lesabre just tryin to figure out what it is and where to get parts

 

ever heard of eaton.com?..they sell part for rear ends

 

If original it is a BOP 8.2. Get the gear options from Board member, Monaz. He is a rear end specialist.

 

It is original, thanks for all the in put!!! It's good to be sure of what you have before you go and order parts! Nothing is worse then tearing your car apart and realizing you bought parts for the wrong rearend lol
