Unfortunately it doesn't. The earlier gen X-ray is a clamshell style (left and right halves screwed together for anyone who doesn't know the term) full of ribs on the inside and is all closed off at the end. Whereas the gen 4 rear main body is all one piece and so we could leave the space open at the very end for the LOP bar to slide in. Sorry for the bad news,
