did you get an alignment? improper toe and caster can cause the exact problem you are describing.

I have a 78 and I rebuilt my front suspension over the winter including steering. I measured all of the old parts and put everything back in the same manner but it was scary to drive. Very unstable, it would track straight but something didn't seem right. The first thing I did was adjust my toe-in. (It was off about 3/4") It made a world of difference, it drove very well with the exception of the steering wheel being off center and a noticeable camber adjust was needed. (I used the old tape measure to do my bubba alignment)
Last weekend I brought it to Addison alignment and after three hours my alignment was done. My car has not driven this well ever... In the past I hated taking it on the expressway because I felt that I was fighting the wheel the whole time.
You have to make sure you get a 4 wheel alignment. My rear was off a considerable amount.

This happened in my 77' it was steering rag joint. It had too much play, so the wheels were drifting at highway speeds. I think the kit to fix it was about $30.00. Good luck.

A lot of what you describe is often looseness in the rear suspension. And if the rear camber is off it'll track straight as an arrow but feel out of control with a little steering input on the highway.

Did the alignment shop charge a fair amount extra to disassemble the rear suspension and set it correctly, or did they reference the back when checking the front.

Both are considered "4 wheel alignment" but unless you paid several hundred labor for rear adjustment it should probably go to a shop that understands C3s. If your car isn't stock ride height it definitely needs attention to the rear camber.

good luck

A question regarding rear alignment?

how is the toe adjusted?"......is it the shims where the trailing arm connects to the frame?

A lot of the old alignment spes are terrible, too. Go to Vettes Brakes & Products website and click on the Instructions link, then the Alignment Specs link. It will open a .pdf page with alignment specs for several types of driving. Give this to the alignment shop and circle the set-up you want.
