Hi Derek and All
The A7/10 swing arm frame should have a half lug like Sluggos pic 1 and 4
The early swing arm frames do not have this lug from the factory, I do not know when it was introduced
The frame tubing is quite thin so stay away from stick weld
I have a frame that needs the lug removing to repair the crushed tube caused by loose clamping bolts
I need the front half of the clamp for that frame and another for the B33 frame that's another upcoming project
I have mostly carved out a half lug for the B33 frame but need it on its wheels to get the angle correct before brazing it on
I have searched for stand lugs that I could be certain of their quality but so far have not come up with anything
(I know Burton have a stand at £100+ but still holding out to find the correct bits)
The clamping bolt size is 5/16 x26tpi
