WOW!!! Great work I need something like that in both my trucks. Thought that I may had found a 5 SPD. Overdrive to replace my SM420 in one of my trucks, but turned out it wasn't an OD wasn't even the Spicer that I thought it was. Turns out it's an International T-34 made for IH by Fuller. Six bolts mount it to the bell housing and it has a long 1 1/4 10 spine input shaft if some one thinks they can put it to use I can't.
