Little more info I can move spring hangers and perches if needed just didn't know if these jeep axles under a j20 are two wide for the CJ5 but for a little more money than I was already gonna spend for motor I can get this jeep truck and use motor and drive train to upgrade from 3 speed to 4 speed and get 3:73 gears and a wider stance
Plus Dana 60 is Suppost to be a posi trac
Not looking for a how to just is this a common swap and can I still send the old lady to get groceries in the CJ5 when its done and not worry about it being safe
Any thoughts and info would be great
Thanks

If the J-truck has/had a V8 the input shaft of the transmission is going to be way too long for you to use it. The shifter would end up between the seats.

And the axles are going to be much wider than the stock CJ axles.

'84 CJ-7: Yota axles (spartan locked front, e-locked rear) 4" BDS, 1" Daystar & 3/8" shackle lifts, 35" X-Terrains on steelies, YJ Tub & family roll bar, heater blower upgrade, 4.2L w/MC2100 & Team Rush, Warn 8274. Rebuilt 4.2/4.0 hybrid, AX15 and twin sticks/clocking ring waiting to go in.

The advertised position for a topless, dirty jeep girl has been filled......by my wife. Thanks to all that applied.
<------------and yes, that is her.
:-D

Thats right. The T18 used in the Jeep trucks and wagons had a much longer input shaft and bellhousing. So it can't be used in a CJ without swapping the input shaft.
