Hi Trevor, your original engine should be rebuildable with local parts
Napa may surprise you with what they stock locally
I picked up a new brass carb float for my 53 last month
It was in stock in Saskatoon, no shipping or waiting.
And they also had the brake masters and slaves for my 1ton a couple years ago.
For a whole engine go see Amigos in Clavet, they have many to pick from.
And one last note, your Canadian truck will have a few random differences from its USA counterparts so consider than before blindly following most specifications and advice you get online and here, all your tiny parts will have been made in Canada not the USA.
Sometimes they had quite different bits.
