Front Shock Recommendation

Looking for some front shock recommendations for my 68 Barracuda. Currently, the shocks installed seem to be bottoming out when hitting bumps. Front is sitting lower than stock (about 23 1/2" from floor to bottom of fender) Tires - P205/60R15. Not too sure what other details I can provide here to make a solid recommendation. Looking for something a bit more stiff I'd imagine so I don't bottom out.
Shocks don't add support to the suspension, they just dampen the oscillations. You need heavier torsion bars (or remove/cut down the bumpers on the LCAs).
Are the bottoms of your fenders really 23 1/2 inches off the ground?
