Steering geometry & parts issues

[Streetbu]

So I'm in the middle of a frame off and someone noticed my center link isn't perpendicular to the frame and it's supposed to be. The problem is that every single part has been replaced so where do I start? It seems like the pitman arm is too long but from the measurements I can find online, the center to center distance should be 6.5" and it is. That really only leaves the center link which I ordered for a g body... I'm stumped. Anyone have any great ideas?

Is that an optical illusion, or is the distances between the pitman/idler holes and the inner tie rod holes different from side to side. The passenger side looks longer.

Where did the center link come from?

Nope, different distances. Passengers side is 5.25" center to center and drivers side is 4"... I don't remember where I got it from. It's well over a year ago now

Get rid of that. It's your problem.

The '78's must have had some pretty screwed up steering geometry.

This is pricy but by far, the best centerlink for a G-body:

Box is from a mid 80's Cutlass with F41 suspension. It's the quicker ratio g-body box and feels SOOO much better than the 16:1 standard box. I guess I didn't know g bodies had different center links.

I'll drop the $ on stuff that's worth it, but I don't think I need to in this case. I have full RideTech front suspenion which is supposed to eliminate bump steer already.... upper and lower a arms, HQ adjustable coil overs, heim joint outer tie rods, billet tie rod sleeves, etc.

I measured about 6.25" center to center on both the pitman arm and idler arm. On center, both inner tie rod studs are about 10.5" from the centerline of the front UCA bolt. I bought the proforged kit with all the parts.

The engine cradle on the crossmember is offset to one side, so don't take any measurements to the frame or crossmember.
