Nice looking truck you are working on, your rust repair is thorough, without shortcuts!
Good job!
I am another fan in your area, I have always loved these trucks, had a 70 K-10 about 25 years ago and always regretted selling it.
Recently went to Colorado and picked up a 70 GMC Sierra Grande 2500, "longhorn" 402 4 speed. I will have it out this season.
Keep it up, Greg
