Any thoughts on spring selection for a '69 Skylark? It's getting a disc conversion so while I've got the spindles out I might as well replace the springs. Rears as well. Custom 2 dr Htp, 350, AC, TH 350. Not looking to out corner a 2014 Corvette, just want to firm up the ride & improve the handling. I'm going the tall upper ball joint & offset upper control arm shafts path as well. Front sway bar is original, will be upgraded when I can afford it. Ditto for a quick ratio steering box. Got a rear sway bar, 7/8'' I'm willing to lower the car an inch,though I'd rather keep the stock ride height. (which I need to check)
