Alan,
I made a two piece, teak underdash cover but not able to take good pictures so I'll try to explain. You can make a cover of any somewhat stiff material (I used 1/2 inch teak) and it can be covered in vinyl or leather if you follow these instructions:
If you look under the dash you should see a square support tube running from left to right just behind the lower edge of the dash. Imagine a level straight line from the lower, rear edge of that tube forward to rear wall of the trunk.
Now you will need four (or five) small right angle brackets to mount to the rear wall of the trunk. I used carriage bolts to mount each angle to the trunk wall so all you see inside the trunk is the flat head. To mount the board to the brackets I used 3/16" bolts and fastened them permanently to the angles with nuts. The bolts have to be long enough so they pass throuh the teak board and the board is fastened to the bolts with wingnuts for easy access.
The front of the board is fastened by drilling five holes up through the board and the square support tube. You can reach up behind teh dash and on top of the support tube so insert the bolts from the bottom through the board and fasten at the top of the tube with nuts and lock washers.
You will find it is difficult to remove the board with the steering column in place so the last modification is to cut the board parallel to and right above the column so you can remove either piece easily. Note: The angle brackets and holes in the support tube should be installed in locations to allow both boards ro be mounted seperately.
One last modification I made was to organize and install all my switches (for a smooth dash), fuse block, wiring, flasher, etc to the board. This allows me to unfasten it and swing the board down to expose and easily work on any of the electrical components.
I hope this all makes sense. If not, let me know.
