Sorry, forgot the truck particulars -- it's a '46 2T (6400.)
Sounds like parts aren't that expensive and the rebuild is, hopefully, straightforward. I'm pleasantly surprised that there are still commercial rebuilder options available too.
As I mentioned above, I agree completely with the 'stopping is mandatory' logic. If repair were impractical that's one thing but it sounds like this won't be that bad.
Thanks all,
