Will the stock 261,(in good condition),have enough torque,to make a different ring/pinion-gear feasible? Seems to me that you would have to either down-shift the trans.,or rear-end,every time you tried to climb a hill,of any grade. Anybody done a swap like this,in a T.F./261/SM420/2-speed rear? If you're swapping ring and pinion,HOW do you know which set to order? Do you write down the #'s from the existing set,and HOPE the parts guy knows which set(S),will match? I'm "running"9:00X20:00's,on the rear,F.Y.I. Thanks for the help,guys!!
