I also have a 54 with hydra-matic trans. It was built in Canada at the Oshawa truck plant. At the few car shows and cruise nights we go to it is the first hydra-matic many have ever seen. I have yet to see another in Canada,that doesn't mean they are not out there , but it is rare here and I would have to say it does add a slight amount to its value.

First time I saw this truck I said "That's the one!"
