My fifth gear went so I got it replaced with one I got out of a 2nd hand gearbox I bought.
I am told the box is in good condition (5th gear was perfect), but he said it sometimes crunched when downshifting into third. But I was impressed with the bits out of it I took.
If you need bits this is the perfect box. It is free! Just gotta come pick it up. I am on the road today so call me on 0412 184 470 or I will check my PMs this arvo.
