hi 57,my name is mike.ive been following your build.very cool.i have been building mud buggys and rockcrawlers for a very long time and i love to fab stuff from steal.i have tried many times to use bed rails to make things,ie. battery trays,gas tank mounts ...never with success.the steel is way to brittle and brakes at the welds.i think that the metal tempers even more and becomes brittle.sorry about that,almost forgot.started a new build.a 24 inch crusier,im trying to go full suspension.im cutting up old mountian bikes ,trying to use the mono shock and swing arm
