The OD trans started out in the 70's based on the Toploader. They shuffled the shifter to move fourth 1-1 into the position of third on the shifter then they produces an overdrive gear and cluster to make the original third postion an OD. Years back there was an article on how to put the OD set in the early toploader case to make an OD true toploader. IIRC the OD trans had a different aluminum case and internal shifter somewhat kin to an SR4. -- Mark Price Morgantown, WV 1969 AMC Rambler, 4.0L, EFI, T-5 -------------- Original message ---------------------- From: "Swygert, Francis G MSgt 436 CES/CECM" <Francis.Swygert3@xxxxxxxxxxxx> > Well, goes to show you I don't know my Fords! ;> > > Ken and Andrew both came to the rescue with great answers!
