i have a 78 d150 longbed,with the 318.automatic. what gear ratios did these come with stock?






and something random here..i need the fan shroud,anywhere i can buy it new or used? local junk yards are empty.

 

well i belive that they have a 3.73 gear ratio but i could be wrong i think this cause me grandad has one and we swapped some 3.73 gears out for some 4.11's but he had not a idea if they were the stock gears in it or not hopefully this helps
