Drawings don't exist or at least Rod doesn't share them. Most of the documentation I received from Rod was hand written. I have a RV-10, so I can't specifically address your question. But if I had to guess, he'll supply everything you need.
On the RV-10, he supplies an aluminum 90 degree elbow that will mount to the sump. You take off the AFP mounting bracket off the bottom of the engine. Then mount the FM200 to that elbow in a horizontal orientation. Per Don at AFP, the fuel and throttle controls will need to change (i.e clockwise to counter clockwise or vice versa, I don't recall). AFP made the change at no charge. I did have to cover shipping.
The number on his website is his cell. He does answer it after hours. I haven't talked with him for awhile. He was having some health issues, but I hope he's past those. He was taking some of my calls while in the hospital. I didn't know that until afterwards. Give Rod a call, he does like talking with customers.
