help

ive been talking to the guys on the jeep forum because i have a 94 xj w/ a blown motor. at first i wanted to put a 350 in it but now i havw come across a 74 power wagon cab and chasis. running 318 trans is good, transfercase is good. axels are good. now the questions of the day. where can i find all of the wheelbase specs for the power wagon? and also has anyone seen anthing close to the xj on a 3/4 ton chasis? thanks for any help.
