not a lot no sorry , the ones i had were well past it when they got here , only saved the engines and a few bits . only selfdrives i worked on were hondas n rovers , they a pita enough . im sure blumby does though , very simillar to the autodrive and take a special belt too not just a normal V belt , another member ended up with the drive unit from one of mine .. scrapped the rest was beyond it
so i'll pass on the drive setup yay
