^ mitch is 100% correct. You will have fun no matter hat, but read the rules of whatever league/class you are running in. If it is just track days or parking lot racing, just build it and go have fun. Some classes have restrictions on what you can use and what you cannot. For example in Champcar...formerly Chumpcar. Aftermarket stuff costs points. The Hotchkis kit would be 20 per spring and I think 25 per shock (if adjustable). Frame ties are not required because you have to have a super well built cage. The sway bar would be more.... Now since they have made aftermarket front ends 10 points, you could use a non t-bar with coil overs for less points.. wacky. Just build it and go have fun. FWIW I had a 67 coronet. I went with a PST kit, new XHD springs, Koni front, coil overs out back and a late Abody disc set-up. was night and day over the stock stuff.
