My 66 Service Truck Build Thread

[Captainfab]

For your intended use of this truck, I would look for a 14 bolt with 4.10 gears. The 14 bolts that were under the 1 ton cab and chassis trucks are a little narrower than the ones under the single, and dual wheel trucks with a pickup box. Also since you're bascially building a 1 ton, you could also use a Dana 70, which were used in 1 ton GM's, Fords, and Dodges.
