Interested in the 12 bolt but would like more info. Is it a chevy 12 bolt ?

 

Interested in Buick 8.5 depending on ratio.

 

Also interested in the Buick 8.5 when you have more info on it.

 

information update

 

Where is the update?

 

Looks like first post was edited with new info

 

Correct

 

Interested in gsx wing

 

Dont see the 8.5 ratio?

 

I'll check it tomorrow

 

Did you change the price of the 12 bolt when you updated the info ?

 

Yes,..Not the same rearend

 

Any update on the 8.5 ratio?

Also curious as to differences between Chevy and Buick 8.5. Is the only difference the bolt in versus c-clip axles? Any other changes that would keep me from using it in a 69 Skylark with a basically stock 350?

 

No sir direct swap,..will need a hybrid u joint and possibly shorten tge driveshaft or get one from a 71to 72 lark

 

but yes c clip axles vs the buick bolt in,..certainly nothing to worry about with 350 or anything under 500hp imo

 

Update on ratios
