I looked it all over yesterday, and you wil need some baffle's when you convert a Coupe wich has A-787 as it's TCDS. this applies to all models in this TCDS DEPENDING on the prop used. On some props listed in the TCDS you don't need the baffles. All baffles noted in the TCDS are available from Univair I think and wil cost around $1000 total.
On the CD there is also some confusing wich was the case for me. They say you can use a 1A90-CF on the 85 but we had a 1A90CF, asked Univair and they finaly told me it was the same, the number with the "-" does not even exist.
