Lower Case (pan) compatibility between A1150 or A1211 and A1226

The Lower Case or as Apple calls it the "bottom pan" is damaged on my MacBook Pro 2.4Ghz Model A1226. I have a non working 2.16Ghz Model A1150 and a non working 2.33Ghz Model A1211, both of them have good lower cases. Is the Lower Case (bottom pan) interchangeable between a 2.16Ghz A1150 or a 2.33Ghz A1211 and a 2.4Ghz A1226 MacBook Pro. Some online sellers list them as compatible while others do not. Which is correct?
