67 fastback 289 4v 4 speed suspension

[china3]

67 fastback, 4v, 289, 4 speed, want to keep as original as possible. I need to replace suspension whether stock or an up graded suspension kit. Want to make it nice but a driver. If $$ is not object, and have a choice between relocating the bolts for a stock set up or upgrading to a new suspension kit, Global West, Total Control, Grabatrack, etc....any others I'm not aware of..what are your thoughts? Im told the ride, handling, etc with the new suspension is much better. I hear the coil over systems are superior. Not planning on racing but want to drive it like a sports car.

Also, toying with the idea of changing manual steering to manual with rack & pnion or power with rack and pinion. Any pros and cons with these ideas? Heard good things about Flaming River.
