normal 2 pin beetle pads fit, they do seem to vary on the tightness factor and sometimes need relieving. dont loose the 'r' clips, as they dont come in new pad sets, altho' you can buy them, or use proper lock wire.
From my NOS collection. Mail me if you want some. I think there are two sets of that type, and a few sets of single pin.Gotcha I'm not in a rush, and can't get them for that cheap! What is that price from? Cheers, Patrick
