I purchased a new dash from centerline this past summer for my 74 GTV.
You are right it was very pricey, but once installed and 6 months later the pain and shock is wearing off
Seriously though, the dash looks great and on a scale of 1 to 10 to install it is about a 4. There are some good threads on removal of the dash and how many fasteners there are to remove. Read those thoroughly it will save you a huge amount of time and aggravation.
Good luck
