I looked at the hotchkis bilstein shocks on their website they sell a stock height and a lowered shock. Do those oval track springs make the car considered lowered?
I believe so. I have not run the oval track spings personally though. But I would take a good guess they are going to be pretty low as they are listed as zero arch or something. The Hotchkis springs are low and the shocks that go with them are the lowered ones.
Call Hotchkis M-F and ask them. Ask for Drew and tell them Steve Wall with the 68 Barracuda sent you. If they need measurements I can get them for them.
