So what a time consuming effort trying to find info on the GM Delco 1988 Fiero radio cassette player model: 16040862. My results are: It has V pulleys V diameter of .075, that means it uses a square belt. The belt length measured with a string is 9 1/2", 242 mm. I split a rubber band down the center with a razor knife to .075 that worked fine for the replacement belt. On the back of the motor is a small hole to a potentiometer adjustment screw. Turn clockwise to increase speed if needed. Here is a link to a belt suppler. https://www.turntableneedles.com/8-Track_Cassette_Deck_Reel_to_Reel_Rubber_Drive_Belts
