My 79 sat in a field with 3 freeze plugs pushed out for 3 years. Replaced them and went to a fuel cell (gas tank rust) and I was rolling. Rebuilt carb a few months later and now it purrs like a kitten. Just finished installing 3.73’s and an Eaton Detroit TruTrac yesterday. No whine, howl, clunks, or leaks so far! Go for it.
