1) Which pull it yards have rears for $65? CrazyRay's?

2) In hp and tq numbers how high can i go with a 7.5 10 bolt?

a) 3500 lbs and slicks
ai) without spool
aii) with spool

b) 3000 lbs and slicks
bi) without spool
bii) with spool

c) 2500lbs and slicks
ci) without spool
cii) with spool

P.S. 3) Does using, say, a 4.56 gear as opposed to 2.56, 3.08 etc. allow more power to be transmitted thru the rear thus putting the diff under more stress?
