Darrell, I found this site for spindles...haven't called them yet, tho.
http://dearbornclassics.com/catalog/search?year=65&model=X&super=lowering+spindlesHere's an interesting site, that shows some modifications Shelby did for Falcons, that entails moving the upper control arm it lowers the front end some and makes the car handle better in turns, but the way I read it, it says that tire wear becomes an issue, then.
The 4th chapter explains Shelby's modifications.

As an interesting note; I read that Shelby built 3 '64, or '65 Falcon Ranchero's. Two are supposed to be in the hands of collectors and one is up for auction....I think the bidding is a little high, though....If I remember right, they're starting at about $200,000! You might say that's a LITTLE high, but it's got very few miles on it!
Dang! I've lived in towns that didn't cost that much!
