I have a nice set of t-tops removed from a '76 Pontiac Grand Prix. I am wondering if they would fit on any other GM vehicles from '76-77 - Cutlass, Regal, etc. Anybody know their interchangability?

 

Far as I know the Hurst Hatches will work on any 75-77 J or K57 (formal roof) body style. Includes Supreme/Salon, Regal, Monte Carlo, Grand Prix. They may even work on 73-74 cars.

I don't think they work on 37 (fastback) body styles. Expect you'd have to transplant most of the 57 roof panel and even then things might not line up well.
