I got these drums and I was told they will support my '35 wires cause of the tabs. But I think they must be mechanical drums? They seem wide enough, but will they work with my '40 hydraulics? Also whats a good measurement to take to know if the drums are still able to be turned? Thanks.
they sure look like 32-35 drums. made to work with the wires. not sure if they fit hyd brakes tho. same dia, but i think the hub/drum backspace might be differnt. best bet is to mock them up and see for youself. std dia is 12.00 anything over 12.60 is barely useable 12.80 and up is junk
