My 4-speed has something like a 1.7:1 Third gear. That's a big drop. I've been looking for a closer ratio transmission. It turns out there were several NP435 variants, the best-=looking one to me is the NP435GA, something like a 1.31:1 Third.

Has anyone seen one of these? They could be found behind those ugly GMC V6s of the '60s.
