That looks like a Fedco number so is no earlier than 1926. Chrysler Canada started in 1925. I have a Canadian 1929 Plymouth with a Fedco number that doesn't fit into the code for the US ones - using WPCHRYSLER as numbers. Your code then is ?11024. Maybe the Canadian ones used a different first digit code? Hope we hear from a Canadian Chrysler expert. Maybe your truck is a cut down Chrysler 4. Depends on the wheelbase - 109" will be a 1925-6 model 58, 103" will be a 1927 model 50. That is assuming there is any chassis there.
