might be stupid G50 aero question

I was looking at the front bumpers from the G50 President and the 94-96 q45 and they virtually look identical.  How close are they REALLY?  Will a front bumper from a q fit on a president conversion?  Also, the 90-93, the only difference I see is the piece where the grill would come down on the president hood.  If that is just removed would it be the same as a 94-96?  

Might save me some cash when it comes to importing a aero kit in the future.  

Sorry if it sounds so freaking newb.  I dissapoint myself sometimes but this is an honest question.

the light/hood line will be different and probably where the bumper bolts to the fenders.
 
i don't really see you saving any money going w/ a pres kit over a g50 anyway. it may open up options on a 90-93 but the front ends are so different that i think the better kouki/pres kits would look funny (i considered the same option at one time).

Pretty much any and every conversion has been done or tried especially bolt on ones that require little or no fab. As mentioned everything wouldn't line up so if you really wanted to do it you could but to do it right you would end up needing to weld and paint.
