Trying to help a friend find a timing belt for his 1996 prelude 2.2

It is an import and engine code is F22B, tho the motor factors said it could be either BA8 or BA9.

Does anyone know where this BA8/9 would be so i can check to see which tensioner he needs to get?

They dont keep the parts so cant order both as they wont accept returns on the one thats not used.

Thanks
