Looks like the V kit includes both wing sets while the non-V might be a single wing kit. Skygeek has the non-V in stock, which shows only one set. A call to them might get the best answer.
Yes. Piper SB 1244B called to install kit
#665-106, but SB 1304 calls for kit #765-106V.
Just gotta wonder. However, both SB's call out an oval of 8"×5.5".
