Put the gearbox in reverse and then put the gear lever into the reverse position (obviously). When the gear lever is in the reverse position, zip tie it over to the left and make it as tight as possible. You'll then have no selection issues when everything is tightened up. That's how I did mine, and it was bang on first time. :up:
I fitted mine in my garage mate laid on my back. They're proper easy to fit.Did you use a ramp to fit or is it possible on my back in the driveway ahha
