Drop Spindles - PST vs. Magnum Force vs. Fatman vs. ?

I'll re-iterate what 72bluNblu said about getting an alignment whenever you change the height. I adjusted the T-bars in my 69 Dart once to factory height (per manual, A-B measurements) and wore out a new set of tires in a 100 mi trip. It greatly increased the toe-in. By the same token, as the suspension ages and the front sags, you will get toe-out. That may be why old cars have a reputation for wandering on the road (plus worn bushings). You can measure toe-in quite accurately using a tape measure across the treads fwd to aft sides of front tires. You can also sight along the tires at the rears for a quickie (should view ~1" off rears if factory rear-end, etc).
