Detroit diesel bracket set for engine/pulley driven air compressor. Part numbers 89225635, 8922536, 8922639-C. These came with a midland engine mounted air compressor from what I believe was a 453; however I was not able to confirm that fitment through my parts catalog. I used the baseplate and made the remaining brackets I needed to fit the air compressor on my 6v53. These are all that I have left over.
