So the YF carburetor isn't the correct factory carburetor for this truck. I suppose it was installed as an in-service replacement sometime during the truck's lifetime.
Without any other identifying numbers stamped on the carburetor, how do I know what kit to order?
Regarding Daytona Parts; Ron Hewitt and his son Tim own and operate the business. When I visited there some years back he told me that the archives were going to be destroyed/discarded because they had no value to the creditors.
