Are later steel-framed (~'96) Honda CR125, CR250 and CR500 frames interchangable?

[OcoWells]

I was hoping someone knew if the final generation or two of steel frames from Honda were interchangable between it's 250's ('93-'96 time frame), 125's (up to '97 or so), and 500's (up to 2000). IF they are, is there any difference between steering head rake and whatnot on the 3 frames (I know Honda tweaked the 250 frames in '93 and again in '95). I'm just trying to find an alternative to a 1996 CR250 frame as mine is bent beyond repair and there is a local 1996 Honda CR500 frame for fairly cheap. Thanks! :cool:
