I won't be needing these for my 57 Silver Hawk because I have a complete 62 GT motor I'm putting in it. Maybe somebody on here could use them, They've been in desert storage since 1977http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MESELX:IT&item=350204925761. The heat riser works freely but is a little loose and would probably have a tiny exhaust leak.
