I just cked out a 1954 bigbolt for restoration. its a 1954 6400,(I think) I used a vin decoder and its telling me its a 4100. The emblem says its a 6400, The vin is N54t032218 With a 16000# gvw rating, single speed rear axle. The valve cover says GMC (and the bees were pretty mad at that point to get a # off the motor).Im new to the older big bolts so any info would be very helpful. Im bring the truck home this fall. Thanks in advance. cool
