Sorry Dale, I left off my address.

If the arm and spindel are still mated together,then, place over a
large open vise. Let the spindel hang between the jaws and close enough
so the cup straddles the top of the vise. Wrap a shop towel around the
cup so it won't be solid against metal. Get a drift pin larger then the
threaded hole,but,smaller then the square taper hole and knock the snot
out of the spindel. One or two raps with a hammer should free it. The
older Stronglite was 1mm larger then standard. I know there are taps to
renew standard threads as MTB riders are rough on them,but, try Yellow
Jersey in Brooklyn?? He may have the over size tap. I'll get his address
and send it later today. Good luck.
