Careful, just because something fits doesn’t mean it’s compatible. Unless the “powers that be” sign off on parts being used interchangebly between manufacturer types then they can’t be mixed no matter how simple the part.

Our windows have a placard that states it may be used for both the EMB-120 and 145. I’m not saying that Boeing didn’t bother to cross-certify parts but I’d be hesitant to assume that parts from a 40 year old Boeing are permitted to fit a 4 year old Boeing. Boeing probably didn’t even bother with such certification knowing that no operator would have a fleet that incompassed both the 707/727 and the newer 737NG or 777. Even if they did have both it probably wouldn’t be for very long (ie Continental phased out the 727’s as the 777’s came online).

It was a statement designed to show that the parts are virtualy identical. Not that you’d actually do that.

I should have made it a bit more obvious that I didn’t mean it in a literal sense.
