API Tailwheel on certified airframe

[user 8073]

My 1997 S2B came with an API tailwheel installed and no paperwork included in the logs. I've been asking around and some people say it's a simple, standard STC while others say it's a complicated 337 that needs engineering diagrams and field approval. I'm pretty new to owning a certified airplane (I've owned a Starduster Too for 10 years). I want my logs setup properly and I know that lots of people have legally mounted the API tailwheel on Pitts S2B and S2C airplanes. Anyone out there know anything about it? Anyone out there willing to send me a pic of your own logbooks/337/STC etc?

thanks a bunch!
