85 K100 matched final drive and drive shaft. Since it's from an 85 it has 16, not twenty, splines at the drive shaft/final drive interface.
Splines are in great shape. (see attached pics)
Drive shaft U-joint is nice and smooth along both axes.
The rear rotor bolts will need to be drilled out. Their heads stripped so I drilled them off.
$425 for both to any US address. USPS money order or cash at my house in Seattle.
This will bolt right up to any year K75/K100.
