I have a 64 LaveyCraft for sale, setup with a BBF 390. Everything is like new, except the interior. I just had the floor redone and I am in the process of re-rigging it now, with a new rudder, split case casale and pulley steering. $4k I can go a little less if I dont have to rig it.
This is one of the best Flatbottoms made, it will handle the chop, great all around.
