I am looking to buy a new stereo to replace the original in my '77 and then put in new speakers. I have seen that some sites like Ecklers sell modern stereos that look like the old ones. I've been told that buying off-the-shelf newer ones will require cutting the dash console to make a larger face for the newer stereos. I really don't want to do this, but I've also heard that retro-styled ones that fit the original faceplates tend to be of lower quality. I'm looking for any input, and if anyone else out there has done a similar project or has tried out the retro/styled stereos.
