Yeah, I already have mine welded on. It would kind of suck to be driving down the road and have your quarter panel fall off. Actually, it probably works just fine. The welding didn't take nearyly as long as i thought. The mock up and getting peices to fit and getting alignment was a different story. I did the dutchman panel and trunk gutter as i was doing the quarter. not a lot of fun, but i was impressed with myself after i actually finished.
