Wanting to know if the power steering box from a 70 gtx will fit my 72 Challenger. I am wanting to trade one of my buddies his power box for my manual box. He races his, I don't so it would be a good trade for both of us. I looked it up on Napa website. Both cars have the same number for power steering box, so I fugure the manual box would work in his car. I am mainly just double checking myself, and I figure someone here would know. Thanks for any help.
