I have two swing arm transaxles for sale. One is a rebuilt stock short tube transaxle with less than 1000 miles on it. Running perfectly when removed from my Speedster. Has the stock R&P and gears for a 65 bug.
The other transaxle is long tube and has the specs shown on the attached pics. The R&P is a 3.44 with a .89 4th. It has less than 100 miles on it but had an issue with popping out of 3rd gear. Make a reasonable over and either or both can be yours.
