i guess if you want to look like a caprice with 12 in omni rims, i don't see why not. but it will probably be an excessive load on the little tires. pretty sure that the silverado is 6 bolts and the s10 is 5 though. hope this helps
i'm not sure the 95 rims will fit over the brakes either. since i'm thinking the 95 is running 16in wheels. And i know the S10 has 15in wheels.
And the lugs are five on the S10 and Six on the silverado.....i'm pretty sure.
