David at Rancho just called and they are shipping the Pro Suby Rhino cased transaxle they just finished building for me. It is a twin of the trans in my Speedster. It will work well with the torquey type 4 or a Suby engine if and when I go that route. I love the one I have in my Speedster so ordered one to replace the squealing transaxle currently in the Puma. I should have the engine and Trans ready to go in before the months end.
