dutch you are a star, get you a beer for that
and some of that karma sutra stuff because I can't do piccies-------yet!!!!! . I have measured some bits and mine is a 54/55 swing arm , even though this doesn't answer the wider hole where the spindle goes through the swing arm....- here goes number 30-- 1/9/16ths number 29-- 17/64 or maybe originaly a 1/4 and its grown / spread a bit haha.-32 is 8/7/8ths with 1/1/8th thread and a 6 inch long length from the shoulder to the threads, and is 11/16ths diameter. bearings are RLS 7-2RS 2 inch dia 7/8 inner--- 7 inch between swing fork, maybe this helps
but I do know the stub axle that the spindle screws into is shorter than A 65 stub axle,,,, its now nearly time for the barlypop shop
edit / swing arm hole a clearance fit for the spindle about 45/64ths give or take a bit of paint
