[oletrucks] door post id plate info needed

[OldGMCtrck@aol.com]

I need to replace the door post i.d. plate on my 1950 GMC 1/2 ton pickup.  I 
have the Serial number, but how do I determine the certified net horsepower, 
the RPM and the maximum gross weight?

The plate was not there when I purchased the truck.  Any help is greatly 
appreciated.

Thanks,
Johnny
