jaros44sr, They work pretty good; but only if you have alot of room to on both sides of the panels you welding together. I really only use them if I am flushing up panels that I cant get any vice grips onto. One thing they helped with in the pictures you saw was forcing the panels to get flush with each other. If I didn't use them I definately would have had to hammer the repro panel to get it to go flush with the contour of the original floor. I hardly ever use them but when I do it makes the job alot easier. If you can pick some up cheap they are definately worth grabbing.
