I am recent owner of an original WTT and Arm combo, and I am really looking forward to setting it up. The silver arm has one slot and the cartridge I will be using has open sides (no threaded holes) below the top level surface, so there really isn't a way to gain a secure point for the one mounting screw. I have read that there was a Fingerlift for the WT Arms which had two cartridge mounting holes in addition to one which connected to the slotted arm. Does anyone know where I might find one of these WTT Fingerlifts? Any help would be greatly appreciated!
