Appears to be a good quality mount but is about 1/2" to 3/4" smaller than my 04 Forester 2.5sohc 5x, I suspect this will be too small for any 2003 Forester. I even tried lifting the engine/transmission to see if I could squeeze it in, but it's way too short. I'll try to make a washer to raise the bracket on the gearbox high enough to fit, will update here if it eventually works, but the bracket doesn't fit as advertised.
