Hey there, im new on here and just got my 1953 GMC on new years... well at least i think its a 53, the previous owner got it in his dads will and believes its a 53 but my VIN says otherwise. The only problem I've ran into is it doesnt have the original engine in it... engine VIN doesnt match on the door VIN, does anybody know how to read them? I've got the truck turning over, just had the carb rebuilt but forgot to pick it up before the weekend, hopefully it will start up now. but i think my vacuum might be dead. is there anyway to tell?
