Hi James!
First, I should have said 'Welcome to the Stovebolt Page'. You'll find this one of the greatest, if not the greatest site for information about that truck. The folks here are really great people and they range from around the world.
Your truck of interest sounds like it is a Canadian 'Maple Leaf'. That was the name given to the trucks that were 'heavier duty' than Chev's.
When/if you get that truck you may want to contact General Motors Canada-Vintage Dept. They can tell you when the truck was made and when it was shipped from the factory. Also, they can provide you with a specification booklet ($25 approx.)
The address is:
GM Canada-Vintage Dept.
1908 Colonel Sam Drive
Oshawa, Ontario, Canada
L1H 8P7
ph. (905)644-4060 (7:30 to 5:00pm Eastern Standard Time Monday to Fri. Fax (905) 644-5436
This is just assuming that it is a Canadian 'Maple Leaf' so time will tell. Hope you acquire it!
Best of luck.
George
