drivehshaft problems?

hi just wondering where i could buy the peices on the driveshafts that the bolts go through?not the shaft but the small metal parts, think theres three of them? would they be the same as on a mk2 golf 1.3 gearbox?

any advice would be great
thanks

they would if they run 90mm shafts. I know mk2 gti are 100mm unsure on the smaller engines
