Question on ride height

Ok, I guess I should have been more clear. I've taken it to at least two different alignment shops, one of which specializes on old cars. They adjust the height, then do the alignment. They test drive it, bring it back to check the adjustment, adjust it again, test drive it, adjust it again. When the adjustment appears to be good, they finish with it and I take it. However, after I drive it for a while (a week or two), the alignment goes out of whack again and it starts chewing up tires. It's not like they just raise it up and not adjust it. They adjust it numerous times before they give it back to me.

I refer you back to post #3.
