I Got a 87 wrangler with a 5 speed peugeot trans. and a 207 t. case. I bought a 90 cherokee for parts and it has a AW4 automatic and 231 t. case. Will the AW4 bolt to my 258? Will the fly wheel bolt to the crank shaft? Will the drive shafts have to lenghten or cut? And finally what about the wiring to the trans?
