Sorry it took so long, but here's the codes from the glovebox.

1G50 : Heavy duty rear springs
1J55 : Heavy duty power brakes

Thing is, now that I'm doing a little more legwork I'm not sure if I have what I think I have (if that makes any sense). I've decoded the vin and all looks ok, I'm just wondering if maybe I have a very well optioned (the sheet is really long) C-10, instead of a "true" heavy half. At any rate, hope this helps a little.
