I have a 1990 (1989 chassis) 345, 454 engine in which the sensor locked up and had to be replaced. It is a plug in and is located between a short cable from the transmission and the long speedometer cable. Unless, you have a "Gear Vendors" unit. My sensor locked up and destroyed the transmission pick-up gear. If you need one let me know and I will provide the company and part number. The new sensor was $20. The cruise control was a DANA. Your year Classic was all mechanical with maybe an option for electronic. In 1991 they went to an electronic unit vss. The electronic vss was attached to the back of the speedometer head (yes behind the dash) if you purchased this option. I have never run into an electronic system before 1991.
