3.73 posi rear question.
I have a question about switching rear ends in my 1971 Cheyenne. I have an oppurtunity to get a 3.73 posi out of a 71-72 GMC. The only problem is I have a coil rear in my truck and the posi is a leaf spring. Can I switch gears between the two? My truck is an original 402 big block with 3 speed on the tree. Glovebox does not say what rear ratio I have.
Any help? |
