What is my 1968 Seacraft

[manitunc]

I purchased this seacraft. it is titled as a 1968. It measures exactly 19' from bow to transom, which is not any measurement I can find from seacrafts of that vintage. shorter than a 20, longer than an 18. I suspect it was rebuilt from a bow rider, but I don't know how to tell. I know the deck was replaced with Coosa, transom filled in and livewell added along with new center console, fuel tank and wiring, probably about 5 years ago. Any thoughts on what it might have started out as? Other pics in my album
