Rut-
If you only need the bushings I think Todd Clark has oilite bushings at Clark Spares and Restoration, for only a few dollars each. CSR's number is 215-348-0595, and his web address is
www.clarkspares.com. He provides replacement engine and vin id plates- I needed one for my 948 after a rebuild many years ago. I just ordered a clip kit from him as well.
I wanted a new pedal pin also, so I ordered a kit from Colin at
www.SpriteParts.com.au. Much more costly at $32 US plus $13 shipping. He also has a roller clutch release bearing that he makes and advertises on Ebay.
If you want to check the diameter of your pin against the one he provided the new pin is 0.43 inches. My old pin is actually a couple of thousandths larger, but that could be the grease layer...
Hope that helps.
Michael
