Tire discounters can’t align my Dart.

My lesson is, unless you are pretty crippled up learn to do it yourself. Unless there is some "really weird" problem such as something bent / broken that you haven't found, it is just not that hard

WHAT YOU NEED

1...A level place aka slab. I don't have, so I jack up my car trailer level after the car is loaded, and use it for a "rack"

2...An accurate way to measure tilt (degrees) reference to level. There are many ways to do that esp. with all the digi levels available, OR buy a caster/ camber gauge BUT YOU DON'T need one, just something to measure tilt

3...Something for "turn" plates and to allow the suspension to "settle". Many things (do a search, front end alignment turning plates) and there are ALL KINDS of solutions, including greased scrap sheet metal

4...You need something for toe. "Crackedback" says he just puts a pair of short 2x4's against the tires jacked up on soda cans and then measures between, front and back. I actually got myself a toe gauge (that I had to modify)

Listen, I'm 73. It would be MUCH harder for me now, than a few years ago, BUT I COULD. It would take all afternoon.

Other than that ?? an old school garage or even semi retired. Search around your area, even body men often are good alignment guys because some of them worked with frame racks and chassis straightening, etc

One of the best alignments I ever got "back then" was a body shop--I knew the owner and "first officer"
Your Right-On, 67' Dart. I had an alighment problem with my 72' Dodge Van many years ago and took it to several alighment shops that charged, but made no difference. I did take it to a local body shop that said the frame was bent. I was skeptical, but allowed them to correct the problem. The issue was corrected, finally. I also, and still do have the same problem with my 69' Dart. Have taken it to several Tire shops and each have told me, it is not correct, but it is the best they can do. I also have installed all new "MOOG" parts. Old timers all hard to find, that are willing or able to work. A solution may be, a directory of "OLD SCHOOL" mechanics, not just a part replacement guy.
