I just got a really great deal on a set of the Scroth 4 point quick harnesses, only issue (potentially) is they are out of a R56, and I have a R53. I got them just to secure them and figured I'm happy to pay the shipping if I need to return. All that said, does anyone know if these will work? The install points seem the same and the only hang up I can imagine is the male tabs, king of a critical point. I've read that the R53 harness can be put into a R56 with very little issue, but is the same for the reverse?
