Check for the use of any rubber in the suspension linkages and mounting components, such as bushings, inserts or collars. The top of the rear suspension (strut?) may be rubber-mounted to the body, and old or worn rubber has sagged and let the top mounts move inward and caused the neg. camber. Toe-in and camber will wear out a tire quickly; the rear end of a front-wheel drive should be tracking straight ahead with no toe-in and no camber. i have built up a kit to do my own alignment on numerous vehicles over the years using basic tools: level, square, jack stands, string, vernier calipers, tape measure, small metal ruler, metal plates, chalk, wooden spacer blocks, binoculars, etc. Just need a fairly flat and level slab of pavement somewhere to do the setup and take measurements, then use a little trig and a calculatus device to know what you got...
