Hi Tikiteck,
Welcome to Stovebolt! It's a great site for many reasons: great folks and just a wealth of free flowing knowledge!
We have a 55 Grumman. It's still pretty much original, but I did install an overdrive (56, R10) unit on it. I use it for camping. I'll be glad to share what I know (that shouldn't take long
).
Mill Supply is a good source for Grumman parts. I'm usually around everyday, but if you don't get an answer to what you're looking for, feel free to PM me.
They are great utilitarian trucks!
Good luck with your project!
