Thanks everyone!
OK, finally I have some spare time for updating, going back in time to Utah and the front suspension assembly...
This shot shows the Speedway Motors circle track "spindle savers" installed. Not sure they're necessary but they're a little extra inexpensive insurance and should eliminate any potential flex in this area.
...and my custom front 10mm thick, hub
and wheel centric spacers for the front wheels. Next to them is the universal 3/4" spacer I used with the GTA wheels. With the custom ones there's no slop in mounting, so there's no driving vibration caused by the spacers getting offset when mounting the tires.
I measured, re-measured, and repeated the process several times to be sure I had something that would fit without issues. It paid off, there's barely room between the caliper and the wheel but it keeps the wheel/ tire assembly neatly tucked under the fenders and now there's no rubbing while turning.
