In a perhaps futile effort to improve the ride, I decided to replace the front shocks of my '71. I believe these may be the original ones and they don't seem to give at all. Probably frozen. I bought KYB rear ones from Rock Auto but their website is impossible to navigate; NAPA and AutoZone don't show them; TRF calls their OEM types cheapos made who knows where; I can't see spending $$$ for Konis, so... what do I do?
