Bump steer problems - Camaro 1967

[BlueBull]

Hi all.
I have a big problem and need some advice. My car is really terrible to ride. I need to spend 100% attention steering it and it uses the entire road!

I'm not sure what the problem is but here's the story.
It was a manual steering car original. I bought a used power steering gear (probably from a 69 camaro)together with the pitman arm and the center link. I used my original tie rods and idler arm.

At the same time I replaced my wheels with 235/18"/40. They are wide and flat!

Something does not match but what?

How's the bushings? Ball joints and alignment? Is the car lowered? How was it lowered if it is?

If it's a first gen car start here (http://www.pozziracing.com/first_gen_suspension.htm)

It's a 1967 camaro convertible. It's not lowered and all the bushings and joints are new.
Thanks

Have you had an alignment done?

[BlueBull]

No I have not. Because I think there is something incorrect with the parts used I haven't done this.

I think I will remove all the steering parts from the car and compare with the old parts. I'm concerned about the center link size. I read there is one with a small center link is (.950") and a large center link (1.125"). I'm also concerned if the idler arm dont work together with the pitman arm used.

When I installed the PS I combined existing parts with the purchased used parts. I'm not sure if there's differences so I may run into problems like this. I assume the control arms are identical from 67 to 69 with or without power steering. I compared, not so accurate before assembly and diden't noticed any differences.

you probably have too much toe in, which will make a car super darty and wanna go which ever directionb the road is pitched.
check toe, set to 1/16th toe in

at the same time get more positive caster
those first gen camaro dint have much causing the steering to be light and imprecise

Be sure you have the correct parts. I've seen the wrong pitman arm used, also wrong outer steering arms, causing HUGE bumpsteer issues. Nothing like having your outer tie rod ends 2" higher than stock!!!
My web page shows lots of stock parts: http://www.pozziracing.com/camaro_steering.htm#Steering_linkage

Your steering arms should look like this:

Thank you all for great input.
I compared the parts and everything looked correct. Some simple adjustments and test driving showed that the car behaved much better if I reduce the toe in and now have almost zero.

I now ordered a total adjustment on a workshop witch shall be done in 2 weeks from now. Anyhow, the car is much better now and normal driving is great.
