Body flex while steering?!

The title kinda says what the problem is but what's going on is when I'm steering my car there are hard spots equally spaced about 1/4 turn from each other. I tried bleeding the system and still have hard spots so I had a friend of mine turn the wheel while I looked under the hood and noticed that when he hit the hard spots the whole body would flex away from the frame and gear. 5 years ago I took the front sub frame off the car and restored the front frame and am just getting back to where it is drivable again. Is it possible that my sub frame is sitting too far back on the car and needs to be moved forward a bit? At the time of putting the frame back together I had no idea that it should be measured for the right fit. The car is a 1972 Nova and there is no steering shaft on it, the column just bolts straight to the coupling joint/steering gear. Thinking back to the 5 years ago when I was reinstalling the frame and not really knowing what the hell I was doing I remember having to really fight the steering gear box to get it to line up with the frame (pushing the gear toward the car). Well anyway I appreciate any help and thanks in advance!

The first thing I would do is see whether the steering box was the cause or not by disconnecting the center link and turning the steering wheel, checking for the tight spots.

If not the gear, while the gear is disconnected, jack the car up on jack stands and turn the wheels left and right by hand, using one side and then the other to feel for binding.

Your car is rear steer, see that there's nothing contacting the back side of the X-member as the steering goes through a full lock L to R turn.

The fore and aft position of the subframe to the body doesn't really affect the steering per se, other than the way the column fits the dash. Otherwise, the steering, etc. is independent of the body.

There should be "witness" marks left from where the original subframe bushings/mounts were located, I would use those as a guide for reattaching the subframe to the body.

If you used lower-than-OEM body to subframe bushings/mounts, they could cause the steering column to be in a bind to the box. If you suspect this may be the case, disconnect the steering column from the box and rotate the wheels left and right w/the center link connected to see if the "feel" changes.

There is always the chance the subframe is out of plumb, caused from a collision. Now that it's reinstalled it's harder to do, but you can measure it for being out of square.
