a firmer ride and more responsive steering
'71 Ply B-body, U-Code...
I did the following when I went through the car...
Urethane front-end 'components'...
OEM 'hard parts'...
Gas shocks...
One leaf added per side to OEM spring pack(urethane bushings)...
OEM rear sway-bar...
Alignment specs are OEM...
HAD 255-60's on stock 15x7's(w/radials)for many moons...
A handful with manual steering...
235-60's up front now...
I can two-finger it comfortably with no problem...
Haven't touched the alignment specs in 20 years, and 20,000+ miles of driving...
