I have a couple of 4 speeds (along with column shifter, linkages, etc). I was planning to replace the three speed in my '67 Heavy Duty (240 engine). I had second thoughts because the 4 speed was much smaller than the three speed. Didn't think it was strong enough. Still setting in my garage along with a bunch ( I mean lots) of other Econoline parts.

Bottom line: I want to end up with a van having front disk brakes; 4 wheel drive
(positraction, of course); and power take off, if possible.

 

While you have some good questions buried in here, we frown upon selling, or even trying to sell stuff.

Ford = Limited Slip. Posi or Positraction are GM/Packard/Studebaker terms.

 

Thanks for the heads up.
