Rear Diff Crossmember to Chassie Plate Part no

Rear Diff Crossmember to Chassie Plate Part no, I've a 2004 2.0 NA Forester and the NS Diff crossmember to chassie plate is corroded, I was wondering if any one had the part no for the plate/s, I'd probably require them both as OS is looking not far from breakdown as it's corroded also, it's just gone through the MOT and this is just advisory as the hole is small at present. if anyone has good ones available a deal could be struck.

Thanks in advance.
