Hi Don, The reason that I am confused about the Speedway adaptors is: They look like they would center the wheels correctly, but the early wire wheels have flat "landing" spots outboard of the lugnuts, and the early brake drums that matched those wheels have "landing" spots inboard of the lugnuts. Later brakedrums do not have the landings inboard of the lugnuts. I read once that without the proper adaptors that support the inboard part of the wheel in absence of the original brake drum "landings" the lugnuts will distort the wheels in that area as they are torqued down. Makes sense, but I know folks that have run these wheels sucessfully without the adaptor that seems to be unavailable anywhere. What do you know about that? TJ omt
