I had my driveshaft shortened the required 3.75 inches(95 mm) for the 5 speed conversion. I have the engine and transmission in place and it is shifting well. I attempted to put in the driveshaft but it seems to be 1.1 cm too short(with the shaft extended as far as possible. The driveshaft measures 146.6 cm fully extended. I figure 146 cm would be perfect if it was not fully extended. Does anyone have a measurement of their driveshaft length? Thanks. Jeff
