Checking websites before getting here, I saw that the cowl driver vent was pre 52, as Gmoniz pointed me. The bed is definetly a 55 2nd up. Gmoniz also pointed the chassis is different for those years and thats why it might look taller. I don't want to keep you guys figuring my little Frankenstein truck, you all have been great help and pointed shone a lot of light on the subject. I'll try to keep as close to stock possible without being a purist and try to match all parts to the same year. Once I have my hands on it permanently and begin to strip it I will surely bother you again.
Thanks you all.
