My name is Kevin. I purchased my first military vehicle, a 1968 M715. The engine had been replaced by the previous owner with an AMC 360. Using the original transmission a T98 the bell housing and everything that needed changing, was. An input shaft of 14-1/8 inches was installed in the transmission. The other input shaft (10-1/4 inches) was too short. Now my problems start. The transmission went out. I purchased another T98 trans with a 10-1/4 input shaft. Finding a 14-1/8 inch input shaft to install in the T98 transmission has been an adventure to say the least! HELP!
