With the body off the frame we did some repairs to the 4.0L. The rear main seal was replaced, as were the clutch and all the fluids. The factory alternator and A/C compressor had been damaged in the wreck, so new components were order up from RockAuto.com and used mounts were sourced to attach them. Luckily the block was still solid. We also replaced the motor mounts with Daystar units.
