Ok folks, i need 2 new driveshaft roll pins, i know you can get them from the dealers but is there anwhere else ? i've been round all local motorfactors to me + other shops and no seems to be able to help, they are'nt the most complicated of items are they ? surely someone must do them ?
Anyone know how much they are from dealers ? and are they likely to have them in stock ?
Cheers
