In Reply to: 1966 WM300 PTO INFO posted by Gary on Tuesday, March 25, 2003 at 10:21AM :
Found the following info in the July 1996 PWA article by Fred Coldwell. New Process 420 and 420D Transmissions use Chelsea series 350X Reversible PTO with input gear numbers listed as 5-P-208 and 5-P-345. This was follow-up to earlier article which I don't have.
My 1967 Dodge Trucks Service Manual lists the PTO for the WM300 as model number 12546.
I'll check the PTO # on my 1967 WM300 later this week to confirm.
