Well the ATS spindle is the best, bar none, $695 for a Camaro. The Ride Tech tall drop spindle is a great bargain at $300. And being tall it gives improved camber gain along with the drop.
I will probably use ATS with my 69 but the 68 is not really a PT car. It was my 1st project with my dad and grandfather. It has been stockish for about 10 yrs since we restored it. We just wanted to lower it with the addition of the 17' billit ralleyes. I ended up going with a 2' drop spindle that works with OEM Disk brakes for right under 200 bucks. I will post pics after the install. Thanks guys.
