NOS GM AC cruise control transducer #25030251. NOS in unmarked box because it came out of a kit. It's a 3 wire transducer with too many numbers + aps to list. But...it's right for 1970-72 GS at a minimum. Equal #'s 36-102 Cardone, 06466184, 25030711, 25030878 and a wazillion others from the mid 60's up to the 80's, 'vettes, Regals, T/A Firebirds, Monte Carlos...it's one of the most common yet hardest transducer to find. That's dust you see on it in the last pic. Discontinued from GM $150.00 shipped US 48 no core needed
