I'm looking of upgrading my 10 bolts. I guy in my area is selling front dana 44 and rear dana 60 with 4.56 gears and detroit lockers. They were in an early 80's Ramcharger. So my question is due I just have to cut off and reweld the spring perches or is there more to it. I figure the dodge will have a different center to center distance between leaf springs. I know the rear driveshaft will have to be cut off and rewelded with a different yoke. But not sure what else might differ from a chevy dana 44. Thanks for your help.
