converting 19 foot bow rider to center console

[65Bowrider]

You have hull no 521, suggesting it was built in 1967.
I've been logging hull id numbers for the Bowriders whenever I can find them. And so I have added yours to my list.
List includes: a 1967, hull id #512 AND another 1967 hull id #534. You number fits between the two.
Does the title tell you anything?

I have to agree with GradySailfish, there are a lot of CC's out there, and not too many Bowriders...so you don't have just a "classic", you have a "RARE classic".

If I can be of any further help, let me know.
