Ok so lets really talk K-members here Folks
What's not perfect about it?
What's your alignment specs? Is it an old p/s box? What size T-bars and sway bars do you have?
Really it's just the steering. I converted from power to manual (very happy) but it was a used box, so it is just a little loose (but very drivable).
As for the rest, the entire front and rear was rebuilt:
All Moog ball joints and rubber bushings (except strut rod, and rear leaf spring bushing, those are MP poly, and Firm Feel poly, respectively)
LCAs are boxed
Addco front and rear swaybars
MP .89 Torsion bars
MP HD Leaf Springs
KYB gas-a-just shocks
Also considered Firm Feel Tubular upper arms, but the cost didn't seem worth it on a street car with 15 inch tires.
There is a new steering column waiting to go in because I am converting to a floor shift setup. Since it is a manual steer column it will also allow me to get rid of the column adapter. Might consider a new box at that point, but this one has got me by for several years.
