Those pretty much went out with high buckle shoes.
Try Lou Czarnota @ (949) 378-1590 (supporting TB.Com vendor / supplier) or
Mike Dobbins in Seattle, I believe @ user name M233roller on this forum.
Mike rebuilds / reconditions them with new paint, rubber, & SS bolts, washers, & nuts.
Brian @ GBodyParts (supporting TB.Com vendor / supplier) might have some.
Glen at NOS4GN might have some, & lastly, you might want to consider posting under"Parts Wanted" section.
