Sad to see that. That's the plane I was originally trying to buy last winter. I talked extensively with the original owner (actually his brother - the originally owner died before finishing it). The plane was completed by an EAA member somewhere up North there. Hope you got it for a good price and the engine is ok after the prop strike.
I think some of the differences from 6 to 7 depend on when the items were purchased. Mine is a 6 and when I got the FF forward kit in the fall I'm sure I was told it's the same as the 7. Nothing it mounted, so i can always take pics or measurements for you.
Also, I may have an extra flapperon (not sure which side off hand) if you want to take a look. It has a bit of damage to the skin where the hing tore through it from being compressed during travel.
