I have been asked to assist a young friend in early June with the refurbishment of a 901 transmission from a 914 (1st and 2nd gear synchros require renewal). I note from the shop manual that a couple of special sockets are required and we seek dimensions/sizes so we can begin fabricating them ahead of time. 1.) We need the hex size of the "stretch" bolt that screws into the front end of the output shaft; this "stretch" bolt has an extension from the head that forms the speedometer drive. We would like to make the required extended socket by welding a piece of tube onto a standard socket but need to know the tube ID required to slip over the speedo drive gear. 2.) We also need to know the hex size of the nut on the input shaft that also requires a special socket. Many thanks if you can give us a head start with this information. Cheers, Jim Sims
