Yeh, I did a similar thing using AR60 axles, the thread is on here, but I got fibrelyte to cut the chassis plates for me.
These are going on the ends of the antiroll bar and hold the rods that go out to the lower wishbones:
drilled them all with holes at the same angle (harder than it looks)
and they fit like so
Did a bit of work on the top deck, I originally filed the curves by hand wich is rubbish so I set up a little jigg on the mill so I could cut the same angle on all 4 corners.
thats it for a couple of days
