I hate automatics

[OLDBLUE76]

I have a question for you all. How hard is it to change a truck from an automatic to a manual transmission? I currently have an 82 1/2 ton 4WD with a 350 motor and a 350 transmission, I also have an 83 1/2 ton 2WD with a three speed transmission and a 250 motor. The 3 speed used to be on the column and the previous owner put a floor shift kit in. I would like to see the manual transmission in the the 4WD truck. Anyone ever done anything like this? I'm not a fan of automatic transmissions, but GM was back in the 70's and 80's so finding one of the stick shift trucks is hard. I would like to know what you all think or have done. Thanks for a cool forum also, this is my first post.
