Hey all,
I'm seeking a OEM harmonic balancer #3896966 that was specifically for the 67 Camaro. Rebuilding a 1967 350 SBC for my car and am wanting to install a correct balancer. I've searched ebay and other sites, all are for 69 or later. For 67, the timing line has to be in alignment with the Keyway. On later models the timing line was offset from the Keyway about 10 degrees. If anyone has one available and interested in parting with it, please let me know. Thanks so much. Scott
