Does anyone know where I can buy a replacement Gottlieb system 3 leg bolt plate? It is a long skinny plate with two large threaded holes for the leg bolts, two smaller holes to attach it to the inside of the cabinet and at the top there is a bent end with tapped hole for attaching a ground wire. I found the plate without the ground wire connection listed as LEG-TEE on pbresource and as LEG BOLT PLATE on marcospecialties but not with the bent end for attaching the ground wire.
