I'm restoring a 1955 CJ5 i also have a early 1960's CJ5 mostly for parts. The bell housing on my 55 has 2 rectangular slots one on each side the right side has a cover and the left is open for the clutch arm. The 60's model has a solid casting and a hole facing aft for the clutch cable much cleaner application. My question is can i use the 1960 Bell housing on my 55.
