Hiya kook,
Hmmmm............interesting question.
In 1970 VW made 1200, 1300, 1500 and 1600 engines. As far as I know, the only engine combined with the AutoStick for sale in North America was the B6 series 1600 single port. But I could well be wrong about that.
Anybody in North America out there with an AutoStick (of course in its original configuration) mated up to a D, F, or H series engine?
