I have a 78 2wd stepside. I have been thinking about putting A/C in it for a while. A recent trip of getting 17 MPG (thats not even after a tune up) makes me want to drive it more, I want to go take it on trips to different places to ride dirtbikes, but its not too fun in the summer, not for long amounts anyway. So my question is who converted their Non-A/C rig to A/C? How did you do it? Go with stock componets or an aftermarket setup, like from Vintage Air. They make it really nice and easy for around $1k. Thanks Again everyone.
