1) The Newer the motor the better,but more expensive [img]modules/phpBB_14/images/smiles/icon_frown.gif[/img]
Maybe a 94-98(?)out of a camaro.
2)Trans depends on your choice,auto or manual.They make adapters to fit whatever you want,but personally I would go with a truck NV4500 (5 speed) and a ATLAS ll
transfer case(this might be too long for a CJ5)
3)Not hard but time consuming,just easier to buy a Painless Wiring kit.
4)A/C in a jeep!?!To me that is very odd,but to each their own [img]modules/phpBB_14/images/smiles/icon_biggrin.gif[/img]
