I didn['t get brackets from Kilby. I got them from the same donor motor that I got the York compressor from. Those brackets were cast aluminum, and the bracing strut on top was a 3/16" stamped steel piece.

I've never got anything from Kilby's, so I don't know what they have. I don't even know if the York was used on the I-6 engine -- perhaps someone else here can say. But if you hunt for one in the wrecking yards, hunt for one on an I-6 and get the brackets with the comp.
