That can turn into a can of worms on several levels...
I think the best way to do this is to buy the entire Dash from the parts car.
Otherwise you will be drilling numerous holes in your original Dash!
IF the drilling does not bother you........
After removing the doner parts (Take the whole Glovebox Door then you are only drilling for the Center Filler piece).
I would take the entire Heater Controller too in case it is different than yours (not likely but....).
Make a detailed Template of hole locations and sizes.
The nuts that hold the trim on the Dash are threaded onto Plastic Studs so take time and be gentle.
Another alternative I have seen done once before was to Glue the Center Piece on.
The Studs for the Heater Control and the Radio Knobs hold it pretty snug anyway. The person cut off all the Plastic Studs that went into the holes, glued the Center and used the above mentioned points to anchor it just fine.
Also just bolt on the Glove Box Door.... Taa Daa! Done with no holes and can be Undone with a little glue removal.
I have several of the "Deluxe" Dashes hanging around here so if ya want pics of behind I can take them and post them here for ya. Just let me know.
