Hi Debbie, Kurtis,
I too have an Early 50 3A, I don't have the SN with me but it has the Dana 41 and a 2A hood. Debbie, I rebuilt my wheel cylinders and they work fine, the real issue is getting them set right in the first place. I'm contemplating going to a 10 inch brake drum and have some of the parts, haven't moved on that yet for the same reason as Kurtis, the 9 inch seem to work OK for where I drive.
Triple X is done now except for adding some of the extras, rifle rack, and some other goodies, if you guys have any questions feel free to drop a note here or PM me. I find myself here about every day or so.
Todd
