transmission swaps

I have had good luck in converting standard Chevy left hand bell housing to CMP right hand clutch fork. With extra CMP bell housings being scarce I needed to convert a US Chevy NOS housing to accept the right hand clutch fork location. While the conversion is not as easy as converting an original CMP bell housing to left hand, the original Chevy bell housing were cast for either side and only the machining determined which side.

To convert a bell housing for the other side it is just a matter of carefully drilling and tapping for the clutch fork ball stud and cutting out the side opening for the fork arm. Alignment of the ball stud is rather simple with a couple of center bolts and compass the location can be copied from a CMP housing. In my case I used the very tired and very cracked housing from my C60L. Cutting out the rectangle for the fork arm is done by carefully drilling each of the corners then cutting between the drill holes, careful cutting don’t go past your pilot hole to prevent a cracking point. So as to take up the strain of the ball stud I made a tapered washer so that the lip of the ball was flatly grounded all the around.

If anybody needs more details I’ll post better pictures.
