1976-2000 Chevy/GMC 3500HD trucks used the 10-7.25 bolt pattern on 19.5" wheels. Also certain GM P-series trucks, motorhomes, and workhorse chassis, though I don't know years for those.

The 3500HD wheels have a larger hub bore than the AD Chevy trucks, so if you want to use those wheels, you should use hubcentric rings. You can still buy these wheels new.

I think Ford also used the 10-7.25 bolt pattern on 1987-1998 F-Super Duty trucks, but they were only 16" wheels, and had smaller lug bolts.
