I am actually in the process of rebuilding the front end on my '68 Cuda right now. Here's what I did:
-Got tubular upper A-Arms, adjustable strut rods, and a factory 11" iron
disc brake kit with new 73 big ball joint spindles all from Bill at Reilly Motorsports.
-Ordered lower ball joints for the 73 spindles, rubber lower control arm bushings, a new pitman arm and idler arm all from RockAuto.com. They are all Moog parts. Rockauto had these parts the cheapest...
-I got 1'' torsion bars from Just Suspension off Ebay.
-Ordered a Hellwig 1 1/8" front sway bar from summit.
- Got a set of Firm feel 11/16" heavy duty tie rods, with adjusting sleeves. (this wasn't necessary, just use C-body tie rods, they have the 11/16", It'll save you a hundred bucks, believe me)
-Reinforce the lower control arms. get the plates from Mancini Racing. 22 bucks i think...
Of course, you don't have to get all crazy like I did...It will probably be easier, and cheaper to get a complete kit from PST, or Performance Suspension Components....I was just giving you an example of what I did...
