the Canadian & US versions of the TF trucks are really the same specs, except for the ID codes and tags and the fender series emblems .... for the US TF trucks, Mike B has a
page here with some ID details, and there's a
short run down here of years, and there's
lots of info at the Old Chevy Manual site .... for CDN specific info, the only place I've ever seen is
this pre-55 site, although they do have the CDN
vin decode info for 55-57, which came from an old
Scotts Super Trucks paper catalog .... good luck with the hunt!
