Here's the rundown the truck is a 72 f600 with a five speed tranny and a two speed rear axle. It's for sale out in Chilton tx. I just need to see if they will part it out. But if I'm right on this then that tranny should be the NP545, right?

 

IF it's an NP, it could be a 540, 541 or 542, of which several versions existed. I don't find a 545. Could be a Clark too. You looking for OD for an FE? It could be direct also. If it's orginal, the data plate on the door or door jamb will have a transmission code.

Thanks for the link. I'm about to shoot em an email see if they will part with a couple things.
