Thanks for the replies, I've had a busy week at work so I am mainly working weekends on it. Tonight I relocated the external gas tank bracket to the passenger side of the truck - this will shorten the fuel line as well as make the tank filler pipe easier to access with a jerry can. I plan to fit a fuel filter and electric lift pump to help out the mechanical fuel pump.
Here is a link that will help decode your truck serial number [oldgmctrucks.com]. See the right side lower section for Canadian info.
From this
reply post on Canadian 235 and 261 engines this info should give you a clue on where to look for the casting numbers and dates codes on your engine.
from the first link, I was able to decode the serial number as a 1959 2.5 ton truck. I just about had to stand on my head inside the engine bay, but I made out
3769925 on the starter side of the engine block. I did find this one website that confirms that block number is listed for the 261 engines:

After you have posted 5 times on Stovebolt you will be able to PM members.
If you decide you want a better used housing PM me, I should be able to help.

I would be very interested. I did take the switch apart and it is just the top housing that is damaged. I sucked on the inlet pipe and confirmed the valve itself still functions properly.
I will get the mounting plate cleaned up and see what my options are.
