TCS timer/relay

[Gary Schisler]

I just got back from Carlisle and I have a question for the parts gurus. On a whim, I bought a relay that I believe to be the TCS timer relay. Don't worry, I only paid a couple of bucks for this. This was mounted on the firewall of a 72 convertible,under the dash side of the windshield frame. It is part number 399?297(?). The first questionable numer may be a 6 and the last may be a 7. Any help? There is an "E" after the part number and a VERY faint UCC1350(?) below that. I have looked in my AIM and can't find the TCS timer that I know is mounted on the interior firewall.

The part number is GM #3996297. This is the TCS vacuum advance delay relay applicable to 1972-only Corvettes.

Joe, I just found it in the transmission section and the AIM confirmed my suggested numbers as well as your confirmation. Thank you. It looks like I lucked out.
