Is it hard to weld on the hardtail as for making it straight? Does it need slugs I have a hard trail pre made from the factory metal works the bottom bars look just like the top they are precut on an angle. I can post pics of it also. I want to start to to cut my frame but knot sure exactly were to cut the bottom tubes. It would just cost me to much to send it out pay the price to get it done then have to pay both ways shipping any help would be great thanks.
