Trimming the dash and mounting it is not that difficult. Custom molding/fiberglassing the bezel and getting the heater and a/c working with the old system is were the time and money is. A shop would charge you a lot to do this conversion. In the shop I used to work in, it would probably cost a couple thousand to do, but our customers were paying $30,000 just for the audio/video systems we were doing. If you like customizing and have the tools, I would try it yourself. For some it is easier to do the full swap (dash, heater, computer, etc. ) from the donor. I personally liked the challenge of converting the old with the new.
