Have you set the EB top on the RB to see how big of a problem it might be?
I could see a couple of advantages:
- The roof ribs would be covered. It always irritates me when the ribs fill with water and it runs down the windshield when I hit the brakes.
- A neat storage area (above the front seats) when the top is up.
The last one would mean the front latches would be back from the front of the PH top, but that should work.
Cowboy added some material to a Westfalia top to make it fit a Chevy van.
You may have to do something similar.
Sounds like a good project.
Looking forward to seeing it.
