There some slight differences from '58 to '59 rear suspensions-the '58 use a 4-point suspension with a horseshoe shaped upper link-'59 and '60 use a 3-link with only 1 link on the top. I don't see why you could't use either year frame to repair your truck (yes, I consider them trucks), you may have to swap the rear crossmember to keep the suspension mounts the same. A frame from a station wagon or sedan delivery would be identicle to an El Camino.
