So..there is a tag in the cab below the radio that says poitraction, second owner (who I bought it from) bought the truck when had 6k miles on it. Said plackard was original. Also, has what I understand to be the positraction lubrication tag identifier tag 'T' on the bottom bolt passenger side which is where its suppose to be. This truck was very special order (fleetside, shortbox, big window deluxe cab, v8, 3-0n-tree with Positraction and any chrome option available (both bumpers with arrow caps) and has the 50th annivesary paint job( Anniversary gold/honey biege). It is likely this was a dealer demo showroom model and had the very special option of Posi which they were getting ready to put on the 1959 Apache. Engine was manufactured in April 58 (engined code F404M) and so likely put together near end of the 1958 years run (vin V3A58O112237). It is definitely a DANA (have compared to DANA pictures on internet - 10 bolt w? bottom drain plug) and has a big casting '45' on both sides of differential. Though not very common there is a DANA 45 which is a heavyier duty DANA 44 and is the one with Positraction. My rig was in nuetral when I blocked one wheel and it locked up. So....with all that said I still do not understand how when both wheels are off ground they rotate in opposite directions. So, I know it is rare to find posi on the 1958s so if anyone else knows of one I would be interested. Anyways, because dont find posi on 58s I am still looking for some for validation (from markings) and the opposite rotation thing has me scratching my head. Thanks for responses, appreciate anymore sage advice. Any advice who to contact, etc) on getting details ontruck from the production number in VIN would also be good
