We encountered the same issue with the horsehair breaking up and getting sucked into the intake.
I looked up a filter element in a Fram master catalogue by the dimensions and the only thing I could come up with was something from an English Ford or a Fiat from the 60's.
Try getting some parts dude to look those up for you. We cut the inside metal out and are temporarily using some foam but no oil.
If someone comes up with something that will fit, let us all know.
