Quick question for anyone that might know the answer to this: What other year/make subframes would fit (just bolt on and go) a 2004 300 EXC (US)? I see the part number for my bike lists that particular subframe as being used ONLY in 2004 on 2-strokes from 125cc - 300cc. Mine is badly bent and cracked in several places and really just needs replacement. Any idea if the 2005-2007 subframes might bolt on without issue? Or any other years before or after '04? Thanks in advance!
