they arent expensive new but if you must
just about any rear wheel drive GM passenger vehicle will have the 5x4.75 bolt pattern and use the 9 1/2" drums , that includes the S10 trucks with rear drums /all g-body ..cutlass , grandprix , regal, monte /f-body camaro, firebird,/ a-body caprices and the buick olds pontiac variants

Easy to identify. They have 1" diameter balance weights welded to them. Usually found on GM's that have alloy wheels and no posi. 3rd gen F-bodies are your best shot. Used on B, C, D, F, and G-bodies with the 4.75 bolt pattern.
