There's probably a better way but my car seems to track straight. Haven't quite figured out how to do the rear thrust angle. Need to think about that one.
Centerline parallel found by:
 Mark plumb bob location, farthest apart on rear axles @ identical points. Accuracy here IS critical.
 Take 2 ~equal length strings; join at one end. Exact equality not required. 2/3+ car width may be a good length, each string.
 Place unjoined ends at plumb bob points; stretch joined end taunt.
 Mark joined end vertex on one side of plumb bob points, then the other. Connect vertex points and you have a centerline parallel.
 Rear thrust angle zero'd by measuring from centerline parallel to rim to set toe - I use toe plates.
 Front toe cal'd from centerline parallel w/wheel centered.
(A) Naturally, you'll want to check camber after toe.
(B) If camber's in spec, you're done. If not in spec, adjust and proceed to (C).
(C) Recheck toe; if in spec, you're done. If out of spec, re-adj toe and go to step (A)
Cal's Backyard Bumpkin alignment - workin' OK?
Will post more complete DIY w/refinements soon....
