Reporting question for Tilt Back Leg Kit - Fender

Tilt Back Leg Kit - Fender

I have all the pieces of the kit except the ear type pieces that kinda look like large strap buttons for guitar, that the legs actually rest on when leaned back. Can I purchase 2 of those separatel?

They are very similar, but slightly different. The major issue being that the bass string retainer uses a smaller diameter of screw and with the larger screw being used in the leg stop, we would not advise using a bass string retainer as a replacement.
