I usually use zip-in 1/4" head sheetmetal screws to hold the rocker on, mount the door to check for fit. On the burb a coupla weeks ago I had to move one rocker end down about 1/8" or so. Sometimes you can get them to fit better than they did when new, mass production ya know. Then when you pull the screws just weld up the holes. I find an air drill w/a 3/8" or so bit is much faster than a spotweld cutter.
