So I just bought an 87 740 with a ford v8. It has a terrible interior and I was curious if 940 interiors or late model interiors will interchange. It should be home Monday and I can't really look at the sunroof yet but it leaks like crazy and feels loose/sloppy. Are there any good write ups on fixing it? I'm very tempted to permanently seal it before I paint the car. I hate sunroofs.
