small budget 5-speed

Yes that is true but there aren't many trannys like that. The reason is the gearbox has to be made with dual sideplates so the R&P can be flipped. The VW box was made like this to work with reduction boxes in the early Bus. In fact, VW stopped making the double sided tranny in 1972 for the aircooled. I too am not so informed on what all is out there so who knows.
