Further to my previous post today, I took notes from an old email I got from Lou (Southpaw) the administrator of this site. He noted that the '54 and '55 hold downs were of the spring variety, (I assume the same style-no change), with the '56 being different, then a change made for '57 (change not specified). Pretty sure I got at least one spring type here for '54 - '55 & will follow up with PM. Clay/Lexi
