what about a 413

Grab the BB push button trans, they're worth some $$!! You may also find that the rear has a SG, not uncommon in the big C bodies!! Oops, my secret is out!! Geof

The push button tranny is there! Haha. What's it worth?

It's a 742 rear end. Can't move the wheels so can't verify the sure grip. But does have small bolt pattern.
