I am pretty sure that they didn't make a single application model that only fit the 54-55-1/2 truck- they are adjustable right? I found an instruction booklet that lists fulton model numbers for each type of car and there was a lot of cross referenceing between models and makes you just put the center clip screws in different holes to adjust the width- but it only went up to 1951. Does anyone have a copy of instructions that references the fulton model number for a 54 truck? We could then check what else takes the same fulton model.

It may be the same fulton model for a passenger car or a **** or chrysler of some kind - then at least we could cast a wider net to find the correct visor, and they might be less scarce and expensive.....
