Call New Castle Battery 1-800-622-6733.They are the only licensed maker of these batteries and sell to everyone else,so they become the middleman.
Technically the R79W is what came in SOME of the LS-6 and LS-5 Chevelles.They will not reproduce the R79W because it wasn't used that often(R79 used in Impalas,etc.) So today they sell you the R89W and put on the R79W sticker.The R89W was used in 1971 and up.The caseings are different but no judges really look for that.Also the R79W had differet sized hex head terminals on Neg.&Pos.
