The Jeep trans had the same bolt pattern as the Chevy bellhousing but I had to remove the clutch and flywheel to get it into place. The steering box stuck out too far to go straight back. If I put in rack and pinion steering it would have fit good. I put a 327 in a 55 Willys overland wagon once and used the Jeep transmission with no problems.
