Drew The best advise is come and see me. It should take you about 3 hours or less to get here . I am located 12 miles north of route 80 in Mendota Il 61342. Bring your diff along for a ride . You will be able to see if it would fit in an original style leaf spring chassis. I am building 2 of them. You will see the tools I am using. I am building in a home shop.But beware the place is a mess. Meanwhile Check out my build thread . You will see how close of a fit that an original style diff is. The thread to my build is located here
