The gearbox was rebuilt by JP Race. The fitted the diff at the same time. I do not have the paperwork for the rebuild, I bought the box with diff fitted off a friend of mine, Gregg aka LregG when he sold up all of his polo stuff last year. I ran the box for a year and did about 2000 miles with it.
The preload is quite harsh, Gregg had it set up to go on his 1W which he never assembled.
I had no problems whatsoever with it in all the time I used it, although it did kill a couple of CV joints.
I'm selling it as I have another ATV with grippa diff, and need the funds for other things. At the time of buying this box, I did plan to build two cars, but this isn't going to happen now.
