do the '05 up wheels have a pocket between the lug holes on the back side? the '99 bullits I ran on my 5th avenue did, allowing me to run .75" thick machined 6061-T6 bolt on adapters instead of through adapters like you used. Also, I wonder if you can open up the center register enough with a ridge reamer...this one says it goes from 2 11/16" on up
Lisle 2-11/16" to 5-5/16" Cylinder Ridge Reamer
