I just swapped out my fuel pump on friday and was looking at a gsr cradle next to the rvr 1 and there are a couple of differences I noticed like fuel pump fittings, gsr had a clip type and rvr has a clamp, rvr also has a extra bit on the side too, although I do think between the 2, it could be made to work with a couple of swapped bits, I just cant guarantee it will, I have a gsr cradle I can get a few pics of for you to compare with
