The Jeep won't be used for any hard-core rock climbing/crawling, or run> with 40 something inch tires, just used to tow a boat trailer and some> light off-roading/hunting­.>

Where does one start with this? Is the transmission going to bolt> right up to the 350 (he wants to get the 5 speed manual, so no> automatics)?

Hey, Bill, thank you for the info. I've gotten some figures together,> including what the cost of the AX15 tranny would cost from a wreckin'> yard, the adapters, and some other information. I've got a call in to> my friend to let him know what I've found out. The most notable> information, I think, is that you can buy these things already done> pretty cheap (I love your allusion to the end of marriages which is> probably more fact than fiction; I'll be sure to pass that on since my> buddy's married with two kids <grin>).>

Thank you again.>
