NOS ACDelco RC24 GM 10402081 Radiator Cap 93-01 Camaro Z28 RARE!. Condition is brand new in the ACDelco box. This cap is extremely difficult to find in the RC24 part number. They were replaced by a RC94 part number. The RC94 will fit your car but is not the cap it came with from the factory. You will loose points when having your car judged if you do not have the correct part number on the cap. I know for a fact that the RC24 came on 93-01 Camaro Z28. I believe the 02 had a RC94. Please ask any questions you may have before purchase. The cap you see pictured is what you will receive.
