Want to be sure I order the right replacements. Getting some rot removed from Big Cat's trunk. The worst spot is right around the left/right rear body mounts -- right behind the rear wheels (no doubt salt used to get tossed right there). These won't likely survive the removal process. Is this the right replacement? http://www.oldbuickparts.com/cart/body-mount-1967-74-buick-12-od-p-4469.html Thanks!!
