I'm from Brazil and just got a G506 to start a restoration project and I'd like to get some info about if you don't mind helping.
It has a 001 number stamped on the passenger side frame rail, just between the front tire and bumper. The truck came with no hood numbers, no data plates ou any other original data plate on it, just those 001 in the frame.
The engine is a runner and it runs very strongly, tranny and transfercase are working fine as well.
Engine block number above the fuel pump says 839931. I'll take the starter out just to check which number is behind it and come to post here too.
Here are some pics of the truck, I hope you enjoy and I would be very happy if someone could come with some info too.
Thanks for reading and I hope you enjoy the truck!
