Thanks Stu,
Ordered a pair from McMaster Carr and installed them. Works great. I was able to cover a chip that happened when the cover dropped :dance:.
Not sure I can install the spring because there is a lip all around and the sppring would keep the cover from seating. It looks like I'd have to screw it into the protruding section of the cover which I believe is hollow and thin walled.
Thanks for the reply!
