Please help ID 1977 29' Scarab.
 

I bought this boat recently and am trying to find it's model name. It measures 29', has twin outboards, it's a center console with a cuddy cabin foreword. It has teak decking, I don't know for sure that it's factory, but it looks like it is. If anyone has links or photos of some that'd be great for comparison to mine to know what's all original to it.
