Looking for part #20755 and #20545c I bought operators from you #39-155 and #39-156. They worked great.

Hmm...It sounds like you may be looking for stud brackets. Take a look at both our 39-517 and 39-516. If these are not what you are looking for, get back to us with some photos and detailed measurements and we will search for a replacement.
