Larry took the words right out of my mouth â?? his description could scarcely
be improved. I got so disgusted with the Bendix starter chewing up its pinion
and consequently chewing up the flywheel that I went looking for a 4-synchro
trans to swap in (since I was replacing the flywheel anyway). Finding an OD
trans made it a win-win.
