Will this HU fit in a Grand Prix?

[ClearSights]

Hey, So I just had bought a 2003 Grand Am from a dealership but there were lots of problems with it so I returned it and am about to buy a 2004 Grand Prix GT. Only problem is I had bought a new HU for the Grand Am and not sure if it will fit in the Grand Prix....

Here is the HU I have....

Kenwood eXcelon KDC-X693

Also, If it does fit, what mounting kit would I need? I have one but it doesnt say it supports grand prix's....only grand am's
