WebOLD Burk spring in Terre Haute can make those leaves, I learned from them how to re-arch leaves,bend them cold,if you go to far bend it back. They weren't scared to hurt em !! Got done she rode like a baby buggy,fresh wrappers and thru bolts. If you go there be sure and watch them make big saddle bolts,the work bench is 2 inch steel plate some u-bolt threaded blanks are 6 ft. long !! Coal mine trucks go there.
