I was surprised to see that your 75 has rectangular headlights. As a high schooler I remember seeing the first car with rectangular headlights. It was a 1976 Monte Carlo. Man, I thought that was cool.

One thing to think about. If you have any issues with smooth acceleration, you may need some carb work. Beware that in 1975 GM was trying some different modifications with the Quadrajet carb. I don't know if all of them were this different style (has to do with primary metering, you likely couldn't tell from exterior view). It's something to e aware of if you need carb work. The carb number is on the drivers side of the carb. A vertical flat area. Number is 7 or 8 digits, starts with a 70 or a 17
Great info- thanks!
