I have a 1973 Duster rearend, 8 1/4 with 2.78 gear set in it with a sure grip, I can Not put a low low gear set in it say like a 3.23, the housing will not exept it. I hope someone can prove me wrong ..

Do you have any pictures/info of the two different housings? The thread that you and halifaxhops have doesnt show anything
