Mythbuster: continuing project thread of my 1303 '75

well, you know how the beetle trailing arm bolt has a bigger diameter than the porsche one, and that you need to pull out the porsche bushings and replace them with the beetle ones, to make that bolt fit through.
Now, from your pictures, that hole looks to be too small to use the beetle bolt. That's why I was wondering, if you made some modification to your chassis, to be able to use the porsche bolts
