Opinions: Fast-ratio manual steering, suspension upgrades

Hey guys,
Just wanted to get some opinions on fast-ratio steering gear box rebuilds, and some other suspension upgrades I'm considering.
I'm driving a '64 Plymouth Valiant and looking at going 20:1 on the steering (FirmFeel rebuild). Also adding front and rear sway bars from Hellwig, positive caster upper control arms from FirmFeel, and possibly some Bilstein shocks. Anybody using Bilsteins on their '64 Plymouth? Would love to hear about your experience.
Thanks,
-M.
I have a '64 Valiant Slant 6 and am very happy with the suspension for a daily driver. 1" Just Suspension torsion bars, Edelbrock IAS shocks (NLA), all poly bushings and bump stops except the lower control arm bushings and the steering struts bushings (I used moog at those locations), Hellwig 1.25" front sway bar, Hellwig 0.75" rear sway bar, Hotchkiss rear leaf springs. It is firm enough to feel safe and in control, but still comfortable when I am just cruising. I have stock power steering btw and love it, running 14x6 SBP Rallye wheels with P205/75R14s. The steering is light, but you get used to it quickly. Parking is done with one finger.
