Hi. I recently had my OEM compressor (AMK?) on my 2007 plate replaced with the Hitachi model. However, the OEM bracket is not a perfect fit. Can someone point me in the right direction of getting a solution / replacement bracket specifically for the Hitachi model?

Well the bracket is cheap all by itself:

Thing is you need mounts. And if the new compressor did not come with them, they can be silly expensive for a set. About $100 for all three. Better off finding the cheapest compressor already mounted to one off eBay that is broke, just to get the mounts. Or you can get this one for more which has two of the mounts, then you just need the third.

Here is a listing with all three mounts to give you an idea of what is needed. Still need some 10mm bolts.
