Just a quick glance at the Suburban SPID thread (
http://67-72chevytrucks.com/vboard/s...d.php?t=616029) ...and it looks like the second SPID was a St. Louis truck...Maybe Leon (LockDoc) could correct me on that. But it does look like most were F or Z built trucks...or Canada of course. I hadn't thought about it too much and was just trying to cast the biggest net on the board to try and narrow down my own build date...but the Blazers were only Flint and St. Louis...no reason burbs and panels couldn't just be Flint and Fremont.
