55 2nd series truck vin number

[Sal's '55 Chevy]

First i know alot of people talk about the vins on these trucks i did some research before starting this thread.

So i running into big problems with my vin i know its located on the pillar on the driver side of the cab. Now some numbers and stamped really good and other are not regardless it does match the frame vin except for the letter at the very beginning. Now i have seen some threads on here for examples of the vins and mine looks nothing like that on the title. The one and the cab and frame do but not the one on the tittle so now im showing two different numbers. When i bought my truck the owner filed for a lost tittle and i received it at my house and it does identify a 1955 chevy pk 1/2 ton weight 3600.

Could anyone tell me what you think happened as far as why the vins don't match?
