Not only hard to find, but when you do---------($$$$$$$)---------! Thanx Stewmac, once again! Great service, great product, good prices. Would love to see a FREE SHIPPING policy, however. Would make up the cost in increased sales, I bet? Gb bg

I've been looking for these for a long time and I'm glad I found them here...I used to use the lock washers that came with the CTS pots but I won't have to do that anymore...
