Looking for parts: 83 SeaRay 18'6 cuddy cabin

[Ellardfam]

I am restoring an old 83 searay seville cuddy cabin.I need the hatch for the cuddy cabin,back to back lounge seats,the instrument panel by the steering wheel with all of the coast guard stuff on it(or stickers that say the same things will work).I also need and exhaust riser for a mercruiser 140 4 cyl and a timing cover plate.If anyone has these things or even knows some good places to find them,please email me.Thanks and happy boating!
