Top replacement?
Get some square stock and make a fixture using the other car before you cut it apart. You need 8 legs on a a sturdy frame There are holes in the rails . 2 at the front and 2 at the back of the front rails . And the same on the rear rails . I have seen guys make them out of 2 inch square stock. and set the fixture on a level concrete floor. Ours is made with a I beam fixture it is over kill. I included pictures of ours and others. This keeps all the rails square and in place.
