Trem cavity cover sizes
My 1992 RG750 was missing it's trem cavity cover. I had an extra one laying around..not sure exactly what it came off, but I think a 540S or 540R. Anyway, that cover didn't fit; it was just a hair too big. To compare sizes I pulled the one from a 1990 RG770 and that wouldn't fit either....it was also too big. Long story short i ended up finding something that will work by swapping various covers on different guitars, but it left me confused. I had assumed these were interchangeable but guess i was wrong. I guess I could understand if an S series plate didn't fit on an RG, but why the heck wouldn't a RG770 plate fit on a 750?
