The only 3 meg reverse audio pot we have with solder lugs is a CTS pot found here: R-VC3M-RA. This pot has a nylon shaft.

Unfortunately we do not have this style of pot in a 100k reverse audio. Please send us your product suggestion to see if we can source this for you: https://www.amplifiedparts.com/new-product-suggestions.
