I recently purchased a 49 GMC 100, original tag shows FC101 9036. Previous owner tore the truck down completely and said the original gas tank brackets were on the frame, but the gas tank was missing when he bought it.

Cab is all original and has no provisions for a cab gas tank.

My question is: Did GMC trucks carry over the frame tank to 49?

My understanding was that this was a 47-48 only thing. Unless, it was a late 48 and got title as a 49. Previous owner claimed it as 49 1/2, but its not listed on the title that way.
