I am seeking information on my 1966 Riviera what I know so far is there were 55 boats built in the RXA 33 series only 2 had the 427 engine. mine is one of the two. I am going to sell it but would like more information if possible. The Hull # is RXA-33-2006 http://www.yachtforums.com/forums/images/smilies/confused.gif Thanks Donda
