getting the width i can measure, but does anyone know the depth off hand? i guess i can lay a straight edge across and measure the depth? i was looking at getting the grant 4 spoke challenger wheel as my steering wheel is rotting, goopy, and i broke the horn again. i looked up the installation guide, but i couldnt find an installation kit for my car. im lookin them up on jegs if anyone cares to assist me

 

Any GM hub from 67 will work as long as it is not an air bag column and yours should not be one.

 

nope, not airbag. so a wheel from a first or second gen will work?

 

Not positive about the first but second gen yes. I think the first gens had small column so the wheel might be smaller than your column. I think the shaft and spines are the same though
