Re: Differences between 8.2 and 8.5 10-bolt rear axles
some say that there is a Chevy 8.5 housing that bolts into a 68-72 Chevelle frame, but i've never seen one. there are BOP 8.5 housings that were used in olds 442's and what not, but i don't think that the internal parts are the same as the later 8.5.
the 8.5 was put in every Chevy badged A body starting in 73 when the car was totally redeisgned, but that suspension is totally different.
do you have any 80's Ford Mustangs or Thunderbirds with 5.0 V8 engines around there? if so, it might be possible to put the 8.8 rear end from one of those in your car. the mounting points on the center section are similar to a 78-88 G body- which is similar to a 64-72 A body. it won't be a true bolt in deal, but you'd get all the strength of a GM 12 bolt with cheap and easy parts availability.
