Reply to "Quad Webers - without cutting up the deck?"

Hum, interesting. The answer is technically is yes, you can.
In order to do so you need to shorten the velocity stacks and the auxilary venturis.
I have done this on other cars but not on the Pantera.

The problem is not that they won't fit, because I think they will, the problem is that the carb "requires" an equal amount of distance from the top of the stack to the nearest obstruction (the bottom of the deck) which is equal to the diameter of the carb throat, i.e., 48mm. (1.912")

On the Pantera, I think the most clearance I can give you is about 3/4".
So technically you can do it but because the IDA is a maximum performance carb, the installation would need to provide maximum performance and my opinion is with only 3/4" clearance you will restrict those two throats severly.

However, one could cut a round hole through the deck over each throat and put a round screen fit into that hole. Nah, scratch that one.
