I could use some help
 

I am embarking on a project and i saw a thread in the 911 forum that implied that this may be possible. Could someone get the measurements in the pic to see if there is even a possibility that this may work. I am going to try and splice a boxster windshield and frame and soft top on to a 911 cab body. Thanks to anyone who can help.
