Does anyone know if they're all like that, or did they change at some point. I ask because my 94 C-1500 is different than 4 3/4". Thanks.

A C-1500 is a full-size truck,isn't it? Those have a 5x5 bolt circle.
I was always under the impression all S10 trucks had a 5x4.75 bolt circle.

I didn't realize the C-1500 was 5 x 5. I tried a 4 3/4 on it and it wouldn't fit, so I thought they went metric. My mistake.

I was asking about the S-10 because I'm looking for a rear and wanted to know which years, if any, didn't have the 4 3/4" circle.

Thanks a lot.
