Thanks for responding. I ordered standard 8 lug steel rims modified to 3.5 inch backspace as more standard steel rims have a 4 inch backspace which interferes with the tie rods. I see how you fixed your issue, a very cool idea.
My original three piece rims have a steeper edge in the bell part of the rim than standard modern steel rims which have a shallower angle so the inside rim of the hubcap that engages with the clips can’t fully seat. It’s difficult to describe I’m not sure I’m creating a clear picture. The fix I intend to try is to make four cuts (slices) on the inside rim of the hubcap with an angle grinder at the 12, 3, 6 and 9 position, which hopefully will allow the interior edge of the hubcap to “shrink” enough to properly seat.
Btw, It looks like you simply bolted the clips to the steel rim? Is that a bolt and a nut or a self tapping bolt?
