Sold Massey Ferguson 370 parts

[Highland_hunter]

Apparently I need my head examined, but recently got my hands on a Massey Ferguson 370 and I need a few items to make it whole. I have listed the Massey part number and description below. I understand these were produced by Roper and the Craftsman 3.7 is a closely related cousin. If anyone has a line on a good source or maybe have extras they care to part with it would be appreciated. I am more than willing to compensate and pay for the ride.

046 489 M1 - Air filter
046 490 M1 - Filter cover (whole assembly would be nice)
046 491 M1 - Knob
