Yes, I suppose you can. It all depends on what you want. In my case, 50 years of not being screwed with went down the tubes when Mr. Moron cut the dash for the modern radio. There as many opinions on this topic as there are members, so I'm just offering this up as mine. I really, really wish this had not happened. Yes, I could replace the dash, and yes, I could probably cobble something up to return it to a shaft radio setup. But in my mind, the current DIN radio just doesn't look right in Gramma's Grocery Getter, which is my car.
Just my $.02, YMMV.
For the OP, here's a photo of my dash with the hole where the shaft radio was cut out. This was when I bought it.

And here's shot of what it looks like when I stuck the DIN radio in, to fill the hole and have some tunes. As far as I'm concerned, this looks like a..........."lady of the night"...........in church.
