12 Bolt vs 10 Bolt Rear

[Alan Nyhus]

Why not use a '65-'70-ish Impala 12 bolt housing? The dimensions are close enough that new housing ends will get it to the same width as the later housing. Get a junkyard late model housing and use the brackets on the early housing. -Al

Alan , 65-70 does not have ears on the center casting. They are on the tubes and aim straight ahead. Factory panhard bar is used. Also there are no spring pads on the housing.
Better off starting with a 68-72 Chevelle unit, I would think.

Got it figured out.
Maryland High Performance will fix up the 10 bolt.
Also get them to add a Roll Bar.

They have the equipment and experience.

It is all good.

Yeah...forgot about the cast ears on the center section. You're right on the Chevelle unit.
