I need a replacement Muncie M21 side cover with the threaded hole for the TCS switch. Is there a part number for it? Does it interchange with other GM makes? The female threads are stripped on mine and leaking fluid. Is there any fix besides replacement? If replacement, any ideas on suppliers?

 

If its stripped, I would look at putting a helicoil in it to repair. I don't know if any aftermarket covers have the TCS option. My AGE cover does not.

 

Something like this? Part number 335308. There are several on ebay right now.
