MAS from mercury cougar?

[darthcual]

I recently went to the boneyard and picked up a mas from a mercury cougar 5.0 to install in my 5.0 cuz it flows way better. My question is I reused my sensor in the new housing...should i have used the mercury cougar mas instead? I only paid 5 bucks for the housing and it didnt have the actual sensor in it.
Thanks in advance
