Can anyone advise whether an RM250A, B and/or C model expansion chamber can be fitted to a PE250B, C or N model without modification to mounting points?

I am fairly certain that silencer mounting points are different, but always thought that the three mounting points for the main chamber portion (i.e. cylinder stub manifold, right-hand front frame lug and left-hand rear frame lug) were in the same relative positions for all these early RM and PE models.

Since I lack enough parts to try out the theory for myself, I am hoping someone has already investigated and can advise accordingly 8) .

Thanks & regards,
James
