10 bolt will fit easily. Hump was designed to clear the 12 bolt. Is it an original HK-HT 12 bolt or a Camaro one? 12 bolt is a lot bigger diff.

Ive got a 12 bolt in a Transam,and mate they are really big(as Byron said),I think for
what its worth just use the 10 bolt and keep the 12er for a bigger project,unless your putting in a "REALLY HEALTHY" motor...just an opinion.

HK 1837 or HT 1837M were optional. How many made - bugger all? I remember reading that the Beechey HT was ordered with one.

Mono, if you ever want to sell it let me know. I will be putting a 450hp 427 into my HK GTS327 and a 10-bolt wont handle that. I do have an original XY GT 9" that I pulled out of my red GTS327, complete with GT brakes that I was possibly going to use if it has 31 spline axles. It is a 3.5:1 LSD.
