Anyway, I had a 16" rear wheel with a two hole hub that was on the sandcast, there is a two hole 18" rolled edge rim that came off the sandcast but put on the PO's dragbike.
The rolled edge rim needs some chrome work so I took the 16" apart today, it will go on a 4 hole hub, then back on the dragbike. Then I know wen the 18" sandcast rim it pretty it'll be on the proper hub with the cloverleaf cush drive.
End result, sandcast returned to it's own parts, a beautiful 16" for the drag bike, some parts to scrap and a spare two hole hub.
