John - Per your question on steering shaft in PM. Can't get photos to link in PM so I posted here... These ought to be simple to make.
Pic 1 stock coupler
Pic 2 modified steering shaft and new coupler
Pic 3 & 4 closeups
Pic 5 finished result. It's not as close as it appears in this angle. It all tucks in nicely with no rubbing.
