That's very true! You can never have enough vice grips.. Especially the large C clamp ones. I've got a 24" C clamp vise grip and it was pretty pricey, but has made all my sheet metal repair easy! It reaches where you'd usually need sheet metal screws to hold it in place.
Thanks!! It really isn't to bad replacing a cowl, doing full rockers on the other hand is something I'll never want to do again.
