Cheers for the replies. Its selecting 1 2 3 4 & 5 ok. Its just reverse. It goes into gear but then after a few goes the rod on the top of the selector slips off the ball joint (this is why it feels loose). The top bar is threaded and i assume it can be lengthened/shortened. Im thinkin its either too short or too long (hence slipping off). And its a quick shift linkage.
