3.5" Wildhorse progressive rate front coils
3" 11-leaf National springs rear
Duff front shock hoops, cut and raised, 9012 RS9000 shocks.
Fab'd in-board rear shock mounts, 9010 RS9000 shocks.
Fab'd trackbar, raised mount on axle w/heim, cut down trackbar mount on frame.
Fab'd wristed radius arm, located shock mounts lower and transverse.
Fab'd rear axle traction arm.
Fab'd heavy DOM steering linkage w/1-ton tie rod ends. (couldn't dump 77' inverted Y fast enough)
More pics and verbiage to come.
