I need tips how to mate a Cherokee rear axle to a stock 1940 Plymouth. I want to keep the stock flathead and 3-speed tranny on my car but use a 3.55:1 Cherokee rear to get the rpm down. I already have the Jeep Dana 35 non C-clips axle and drive shaft. I guess I have to mate the Cherokee u-joint in the back to the stock Plymouth driveshaft. I will use a tri 4-link for suspension. Any advice on this?
