On my 73 chally it is made in two pieces. You have to disassemble / reassemble in the dash.... sounds hard but it's not
.
Thanks for the refresher course.
You are right. Take it apart, and insert the bottom half first. That's the easy part. The top half is where I had to do some squeezing. Once you get that in there, you have to re-align the top so that it aligns with the screw holes on the bottom section. Then re-insert screws.
