my mistake - 55.2 started 001001, 56-59 started 100001 - John Gunnell's book Chevrolet Pickups '46-'72 says there were 278,615 commercial vehicles made in '58 - no telling how many at any given plant, but not all plants produced trucks .... I've never seen any figures for Canadian production at all, but by the Task Force years there was only one plant, Oshawa
