Radiator Side Tank: Corvette 84-89 InletGM original INLET Side Tank with the seal for 84 89 Corvette. This tank is Discontinued by GM We have two NOS Inlet side tanks. Figure factor into the purchase of this part the ability of the core to withstand new pressure.. too many times we find people replacing a side tank only to have the alloy Core blow days or weeks later.. or the other side tank first.. even worse.. and the core is not worth the total sum of doing it 2 or three times over and
