69 GMC truck engine

[#169fan]

Can anyone tell me what the origional engine color was in a 1969 GMC 1/2 ton truck.It was my Grandfather's old pickup that I learned to drive in.He passed away about ten years ago and somehow I was able to get the old truck back to Missouri and I am looking to restore it.After Grandpa past away the truck went to his brother out in Wyoming who was planning on restoring it himself.He also past away.The truck came back to Missouri to my mother.I was recently able to talk her out of it to restore.The only condition was that I had to put it all back origional.Grandpa replaced the engine just before he passed.It has about 100 miles on it.He was just an old farmer that did not care how it looked too much so he didn,t bother painting it before he installed it.Any kind of tips that anyone could give me about where to find parts would be greatly appreciated.I will definately be needing new passenger front fender as well as a new chrome grille.
