Re: Differential highway geats
Most guys go to the 3.55 gears. Several vendors I checked sell them usually around 450.00 for the ring and pinion. Here is a set on Ebay for 389 but you might want to do some more searching. http://www.ebay.com/itm/1940-1941-19...25.m3641.l6368
by checking one of the tire/gear/rpm calculators online you can figure out what your rpm drop should be at 65.
This one that Randy's ring and pinion has is easy to use and even gives the rpm for different trans ratios. You want the manual ratio which is 1 to 1
