71 Duster 360 turbo build

This throttle body is from Speedmaster via eBay, but it’s different from the other eBay pieces like yours. Part number pce138.1001 . Is your tps the blade type? The throttle sensor shaft on mine is a half moon shape, and Speedmaster sells their own sensor for $100 after shipping. I cannot find any info on an OEM sensor that works with it, but I’m going to the auto parts store hoping someone patient can give me a hand. I really don’t want to be stuck looking for an outdated proprietary sensor 10 years down the road. As for IAC I’m not utilizing that at this time. I’m using the micro squirt IAC PWM output to control my fan which is a bit more important at the moment.

That should use the standard GM style TPS. Commonly found on pretty much any LS based engine.
