Well, maybe not Hillbilly, but home grown at least.--Set car on reasonably level garage floor and block tire so car can't roll foreward or backward---use carpenter level and felt marker to put a line on floor of garage directly below rear side of rear axle tube, on each side of car, as close to the brake flange as you can get it.---use a reasonably straight peice of board to connect the 2 marks on the garage floor. Use tape measure and measure 112" towards front of car, on each side of car and mark garage floor again. Use trusty board to connect the 2 marks same as at the back. Lay long side of carpenters level on floor, and place short arm against front of beam axle (or tube axle), as close as you can get to the kingpin and mark floor at each side of car. The new marks transferred from the front axle to the floor must both be the same distance from the line transfered up from the rear axle. If it isn't, adjust 4-bars or hairpin clevis's untill they are-----this ensures that front and rear axles are parallel. (this is done making the assumption that the rear axle is setting squarely in the chassis--I know mine is because I built the chassis and 4-bars.) What I do next is to clamp a peice of 1" x 1/2" x 10" long flat bar to the I-beam with a c-clamp on each side of the car, again as close to the kingpin boss as I can get, with the bar extending about 1/2" above the I-beam, and about 6" below it. I have 2 magnetic angle finders, and I put one on each of the bars. They should read at 4 to 6 degrees negative caster (that is to say, top of kingpins tipped back towards rear of car)----both sides should be exactly the same---adjust 4 bars or hairpin clevises to achieve this--(sometimes it is a good idea to have helper with pipe wrench to tweak axle a bit so you can get the 4-bar bolt back in)---he's not bending the axle, he's actually tweaking the spring-pack). I have made up a wooden jig for checking the toe-in, (which should be about 1/8" on cars running a solid axle)---entire front end alignment took 2 hours, start to finish, and cost nothing. Crude as it may sound, I have used this method on 5 different cars now, and they drove straight and never pulled to one side or the other, and never gave uneven tire wear.
