I talked to Marine Connection Liquidators in Ft. Pierce, FL today and they have the classic logo decals in stock (only in teal color though). They also have the new style "puffy decals" with the billfish on them. Give them a call at (772) 465-6460. Actually, they have a TON of classic Aquasport stuff in stock.
Also, worst case scenario, you could have them made at a local sign/banner shop. They can cut UV resistant stickers for anything as long as you have the logo in an EPS format (scaleable without losing quality). I'm about to do this in order to make black decals for my 22' and dark blue decals for my 20'. If you want, let me know and I can e-mail you the EPS file when I'm done.
