Finished my Cobra last summer and went through same issue with springs. Have a big block, started with the 500# 8" springs, drove like a rock. Moved to 375# 10" with great ride and proper height. Used a spring compressor and HD wire ties to get them short enough to install.

Regarding sway bar bought a lenght of 4140 bar stock and formed by own with a hydraulic pipe bender. Works and fits great.
