After cage construction, it was time to mount a different rear diff, original is a bit too weak so the choice fell on a diff from an Opel Omega 3000th It fits in the original rear suspension bridge, so I sanded and painted the bridge. Diff mounted in the bridge and then up to the bridge on the body.
I shared the driving piles up and let the outer part remain. It keeps the wheel bearing in place. Here you can see my SAAB 9-5 Aero front brakes, will be replaced with D2 330mm discs and ok.
