gbodies have the 5x4.75 bolt pattern and the s10 should be the same.

Okay, here's the list of every GM chassis with the 5x4.75 bolt pattern. Please note that the bolt pattern in no way guarantees the fit as that is determined by the backspacing as well. Spacers are available to put shallow dish rims on a G body, but can fail if subjected to excessive loads. For this reason, they are not legal in many sanctioning bodies as it is a safety concern.
Y body-Corvette, XLR
A/G body- (1964-1988)Cutlass Supreme, Regal,Chevelle, Malibu, Grand Prix, Monte Carlo, Cutlass Cruiser, El Camino, GMC Sprint/Caballero, 1985 Bonneville( I think), Le Mans, RWD Grand Am,Century, F-85, T-37, GT-37, Tempest, Skylark, 442, GS, etc. ( yes, I know I forgot some)
F body- Camaro, Firebird, Trans-Am, Z-28
X body- (all with 5 lug, any after 1965, none after 1979) Nova, Chevy II, Omega, Ventura II, Apollo, Phoenix, Skylark
B body-SOME BUT NOT ALL!!! 1977-1991
Caprice, Parissienne,Bonneville,
Catalina,
Delta 88, Le Sabre, 98 Regency, etc. Mostly on low line cars and never on wagons, heavier B bodies got the 5 on 5 bolt pattern.
S trucks- Chevy S10 pickup ,Blazer and Trailblazer ( 1 year only), S15 pickup and Jimmy, GMC Sonoma, Oldsmobile Bravada. Full size trucks are 5 on 5 or bigger and will not work.
