To cut the dash or not to cut the dash?

Okay, so I have a functional AM radio (original) in my dart and want to get a DIN sized radio into the car.

I am going to be doing some stuff to the dash, and have the perfect guy to call to cut the dash. So should I do it? I know this is more of a personal preferences, but I have seen plenty of both on the forums.

I know if I cut it, we will have to build a brace setup in the back to make sure the head unit doesn't tweak the dash.

I'm going to be pulling all of the plastic trim from the dash here soon to get rid of the wood grain look with some very nice gloss spray paint. Just trying to get my upcoming "no dollar" projects under way.
