Alterkation or K1?

Just get the Reilly Motorsports Street Lynx for the Rear, It comes with 12" 175"/# Springs, I swapped Mine out for 200"/# Springs.
And then Build / Upgrade the Torsion Bar Front suspension with Proper 1.03" or Larger Bars, Sway Bar, Good 16:1 Box, Proforged Rod ends and Ball Joints, Skookum Tubular Upper Bars, With Bushings or Rod Ends, FFI Sway Bar, and good Big Brakes. Just look Back at Tim Werner's Red Brick and The Old Mopar Acton Green Brick Car, Those Cars Did what you are asking for but without the Triangulated 4 link out back.
I did all of that on my '64 Dart and its wicked fun on the Highway and back roads as well as the auto X course.
One advantage of putting the triangulated 4 link in is that you get bonus area under the trunk floor fo sinking the Battery box if desired.
