Bob,
I just recently installed a newly rebuilt sideshift trans and 28% out of extra
parts I had laying around. I haven't been on a long trip yet to log mileage
benefits but it really lowers the RPMs when kicked in. The real test will come
at SE Classic in September....Atlanta to Lynchburg, TN. Lower RPMs means lower
fuel consumption. At $4.39 per gallon these days, it should pay off rather
quickly.
By the way, it is matched with the 3.54 rearend too. First gear starts on
inclines only and second gear on level or downhill starts.
