Welcome to MR BUS CO!
Here they are, fantastic pushrod tubes for your type 1 engine! These are zinc plated to prevent corrosion, and have a "windage" end to aid in oil control.
The real benefit of the windage end is that the pushrod tubes stay in the hole in the case when you are assembling the top end of your engine. It makes it so much easier than trying to balance stock tubes while putting the head on.
