Need part # for a GM style 3 wire (heated) o2 sensor

[corvette]

It is not for the TGP, but my IROC. I saw a listing for a Bosch from a Chrysler product somewhere, but can't for the life of me find it now. I need one that mechanically will exact replace the GM style like what is used on our TGPs, but I will have to do some custome connectore work to energize the heater.
I am posting here, 'cause it seems like some of the sharper techies in wrenchland hang here, probabally 'cause of the higher class of car the TGP is. Drop me a PM or post the # here if you know it.
By the way, I may be selling the IROC if any one is or knows someone interested, it runs very strong, engine less than 5,000 miles.

Thanks all, and keep spoolin', not just crusin'
