Yes, as long as the gear ratio will work for that series of differential. I'd be interested in the housing if you were closer.

The '65-'69 B body rears are the same width as the '67-'70 Chev/GMC vans, so they have a following. They also make great shortened rears for vegas!

Re: 68 Impala 12 bolt

I'd check around before I cut it up, B body diffs are harder to find that A body ones and it may bring a nice price from a '65-70 B body owner.

It is a rare man who can count his own blessings and not mistake them for personal achievements.
