Mustang II bump steer, drifting

I have a '74 Mustang II front suspension in my '34 Ford which I actually cut out of a junkyard Mustang II back in '81. I set the front assembly, crossmember included, in the '34 frame with a good bit of work and a careful watch on the installation of the strut rod mountings and location, all of which I did myself. It is basically a stock Mustang II with rubber bushings and the strut rod mounted on a 3/8" plate and gusseted on both sides and the frame boxed inside of the mounting location. The rack is a stock Mustang II power rack driven by a SBC power steering pump with a restrictor to limit the pressure from the GM pump. If I remember right I bought the front springs from a company now out of business called A-1 Springs. I believe they are 300lb springs. The front tires are BF Goodrich radial TA's 205/55 R15 with 26.5 lb of air.

Problems:
1: When I hit a set of railroad tracks or a pothole, I get a lot of bump steer both directions of the steering wheel.

2: The car rides very stiff even with stock '74 Mustang shocks and seems to slam the car way too hard if I hit a pothole.

3. The car drifts in the lane I'm driving in and tries to go either direction if I let go of the wheel. I suspect a camber problem here, but not sure.


Any help on this stuff would be appreciated. I searched through some of the archives but didn't get a hit.

Thank you in advance.
