When redid all the brakes (5 lug) and suspension in mine, I aligned with a level, some string, and a tape measure. I was planning on bringing it somewhere, but like you, hate anyone working on the car. It runs straight as an arrow the way I set it up, and as little as I drive it….. it never went to the alignment shop. I do have to make one tweak on each tie rod end to get my steering wheel perfect, but right now, that’s just another thing in the list.
