1970 Medium Duty Investigation
So i'm currently sitting in quarantine waiting to go to work offshore and of course i started perusing FB marketplace and came across this. Here's the seller's information:
"1970 GMC C 55 ?? Vintage 1970 flatbed truck with a V8 with a 5 and 2. Also an auxiliary transmission that you can shift in low and top speed is around 18 mph. There is a very heavy winch with approximately 150 feet of cable. This truck was used to pull heavy loads at a slow speed." I'm interested in decoding the VIN if anyone can point me in the right direction. I've been searching high and low and haven't come up with much. ![]() ![]() ![]()

Re: 1970 Medium Duty Investigation
What are you trying to decipher? A picture of the spid would tell you more about the actual truck than the vin. Unless you're trying to figure out build dates and which plant it came from.
I got a gmc parts book in storage I could dig out but hopefully somewhere here will chime in.

Re: 1970 Medium Duty Investigation
The VIN says that it is a GMC C6500 that originally had a V6 engine in it, most likely a 351. 5 speed transmission is probably a New Process. Truck was built in Fremont, CA.. SPID should tell you evrything else as CarolinaHD pointed out. Neat truck.
