I bought one of the billet clutch reservoirs from Hawks (see link below). I was going to install it today and the tab end is a little tight in the 4th gen bracket. I figure deburring the bracket might do the trick or a light sanding to the underside of the tab. I'd spent enough time upside down under the dash today that I decided I didn't care and I just put the OEM replacement in place. I ordered this with the new rubber insert (listed as a $10 option, $110 total).
