swaping my 89 wrangler 4.2 for an injected 4.0. help

I have a 1989 jeep wrangler sahara canadian model. The origional trans is the t something 999. Win a fuel injected 4.0 out of a cherokee mate to this trans. I have already taken the engine mounts on the 4.2 block and mounted them on the 4.0 the motoer sits fine in the engine bay but weather I use the fly wheel from the 4.2 or the one from the4.0 the motor wont spin freely in order to lign up the torque coverter bolts. Does anyone have any idea what might be hindering my progress
