I had always thought this was from the movie Grease, but I saw the movie and didn’t see this scene in it. A small group of teenagers needed car parts so they could finish working on their car. It was night-time as they roamed a neighborhood looking for what they needed. They found a car parked on the side of the street and with the tools they carried with them, a couple of the boys acted as look-out the others worked on stealing the car parts. In this scene I think it was a tire or rear fender. Once they got the part, they set-off to find the rest of the parts needed. Thanks so much.
Maybe the LORDS OF FLATBUSH (1974)?

I just watched The Lords of Flatbush, I don’t that was it because they were stealing a car instead of taking parts off it. Almost didn’t recognize Sylvester Stallone, Perry King, and Henry Winkler – so young!
