Dash swap

Anyone know, or has done a dash swap from a 93 to something a little newer, like a 95/96.

With Gm's half-a$$ed version of an Anti-theft stereo, being split into 2 pieces on different places in the dash, I find that there is next to nothing I can to to replace the existing radio. :banghead:

So, does anyone know how much of a hassle it would be to swap the entire dash out from a 93 to a newer dash? From what I've seen, it only looks like minor differences in the mold.

Thanks
