I see what you mean
VW heritage lists the same part no, 111-998-063 in its bus catalogue as for 8/68-7/70, so it should be OK - call them if you're not sure, usually v. helpful
The points should be the same,it's the condensor that could be different.You also never know if the dizzy has been changed previously for a different year one,unless you've had it since new?
Best to phone them as Wannabay has said whilst you are looking at the dizzy.
