1948 GMC Truck Serial decoder??

Anyone know where I can look up a serial# for a 1948 GMC? There is plenty for the Chevy's, but whenever I find something for GMC's its no longer there!
Thank you for any help.
1948 GMC FC 353 2871

 

bc67, try oldgmctrucks.com if it's GMC they know it
My VIN is FC 253 3048. I think, FC = type of cab. next 3 = weight rating. next 4 = sequential numbering.

 

FC 353 decifers to this, "FC"= '47-'50 year model (conventional cab), "35"= 350 series 2 ton, "3" = 161in. wheelbase. "2871" is the production number. Check out www.oldgmctrucks.com for more tech. info, & a great discussion board.
