Well I got the Ford 300. Just about what I was looking for, 90 model, 300 6, 5spd, manual. I don't know whar rear end it has but it is TALL, truck goes 15mph in 1st. Not what I want in a pullin' truck. I'm going to put an air lock rear end in this summer; the question is - do I need to change the whole rear end assembly to get a lower ratio or can I get away with just changing the gears in the rear end at the same time that I put in the lockers? Geeze the problems that just cme to my head. I'll probably (probably?) have to specify the rear end when I order the locker so I'll need to have that taken care of already and would the locker kit fit a hybrid or made do diff. Ouch.
