I second MarkhamWelding.com. I got mine there and am very happy with the price, turn-around time, and the build of the toothbar itself. It has replacable teeth on it, which is a good thing, not that you'll wear those heavy-duty teeth out. /forums/images/graemlins/shocked.gif
Just make sure the side of your bucket are straight when you measure. I ordered one fo rmy neighbor also, and when we measured we did not take into account a slight bend in the bucket and altough the measurement was right where we measured, we had to grind the end of the toothbar so it would fit at the edge of the bucket. Better to go a 1/4 inch too small than too large, is what I learned.
