Found it in my paperwork. We used a generic trunk release solenoid, it has a cable attached to the solenoid we attached to the throttle and adjusted the high rpm with the placement of the solenoid. Any sterio shop or somewhere that installs car starters should be able to get the part. Another option if you can figure out how to mount and place it would be the a/c high idle solenoid off a rochester carberator as it is a solid solenoid that is adjustable. might be hard to mount it on this style of throttle body though. The trunk release solenoid should be easier as the solenoid body is mounted remotely from the throttle body and it is just a cable attachment. Just make sure you dont have it set too high at first. I have one left here so i can take a picture if that helps but i can't seem to figure out how to post a picture here. message me if you want it emailed to you.
