[70.5_firebird]

I just finished pulling the last suspension parts off my 70 firebird front end, and I am going to rebuild it with polyurethane bushings and new balljoints, etc. Too save money I want to use the stock control arms and spindles, but since my driver side spring is broken and both shocks are shot (car has been parked about 11 years), I thought I might use a coil-over shock. Anyone have some opinions on wether the ride is worth the extra money? What brands will work with stock control arms? I also read a thread where someone mentioned a 'taller balljoint', is that for ride height? or does it improve the geometry somehow? Also wondering if there is a performance rotor/caliper bolt on, that allows the use of 14" Rally's. Just looking for something street/performance, nothing too serious.

Thanks for your opinions.
