Those old Chevy trucks are fairly simple to work on but the problem is parts are getting very obsolete for them. Several years ago when scrap metal prices went so high a lot of them trucks went to the scrap yard so it’s hard as hell to find parts trucks to rob them from. Spare yourself the grief and buy something newer and easier to keep maintained unless you hate retirement that much and like working on junk. I have a c/50 and a 60 and contemplated rolling both of them off a cliff and one point or another. And that was just keeping them running good enough to use to cut corn silage…
