If you're selecting by vehicle, and there's no option to choose a RMW, see if it will let you choose a Chevy Astro Van, 1994 or so. (DON'T choose like a 2003 Astro because some time around 1998 or so, the Astro and GMC Safari changed to a 6-bolt lug pattern.)
The earlier Astros have our identical 5x5 bolt pattern, and the backspacing should be similar.
