So for my next year im gonna be running 4.10s in my pulling truck but i have one question. In my pulling truck now i have a d60 front and d80 rear. Gears are 3.54. Now i have another rolling chassis with a d60 front and a d70 rear they are 4.10s. Can i take the diff out of the d70 (4.10s) and swap it into my d80 (3.54). If i can what do i have to change in order for it to work? Can i just swap the 4.10 in or will i have to change ring and pinion? Thanks!

Be easier to find a 80 model 4.10 and just swap it out, then sell your 3.55 rear.
