I haven't read the whole thing line by line but we installed FirmFeel UCA with the BallJoint placed on from them and the factory eccentric bolts on my buddy's 72 Roadrunner 440 4speed. They advertise an extra 4º of built in caster. I aligned it myself using a DIY wheel alignment kit I bought. Toe wasn't a problem. 1/16" of an inch each side for 1/8" total toe...I can't remember my camber setting on it though
