To cut the dash or not to cut the dash?

So was just chitchatting with my friend Joe, who is THE corporate installer for Audio Express (he does the display vehicles for shows like SEMA, etc) He said that we will just make a plastic glove box liner and then build one of these into it:



Details on this kit:

Dimensions:

Overall: W=9.985", H=3.484", D=9.197"; the height of the kit decreases from front to back. The front of the kit measures 3.484" tall and the back of the kit measures 2.596" tall.
Internal Compartment: W=8.534", H=2.516", D=7.511"
DIN Receiver Mounting Dimensions: W=7.202", H=2.123", D=7.493"; the receiver can have a maximum nose width of 7.684" and a maximum nose height of 3.334".
Shaft-style Receiver Mounting Dimensions: Nose Width=4.284", Nose Height=2.126", D=7.511", Shaft hole spacing range=4.707" to 6.235"

We are going to use a new glove box kit to make the template for a heavy (1/4 inch+) ABS plastic glove box liner.

He is also planning the sound system for the car, as this is his thing....lols, I am just tired of listening to the AM oldies station......
