Started on the rear crossmember today. After hours of measuring and scratching my head I finally realised that the Brumby chassis/crossmember is not symetrical !!
you can see in these pics that the mounting holes and the chassis are not identical on each side :
But managed to get the crossmember mounted temporarily so I could suss out the rest of the mounts for the diff hanger and the trailing arms.
The diff hanger is fairly straight forward - I have cut the arms down to length and just need to bang up some stong mounts using some decent angle and fully weld it into the corner between the chassis rail and the rear of the cabin.
The trailing arms are a different matter - once again things are in exactly the wrong spot - 10mm in any direction and it would be a lot easier. As it stands the mounting brackets are wide and flat but the chassis where they sit is narrow and curved. I don't want to modify the chassis if I can avoid it because it is fairly weak around this area anyway. So not sure yet if I am going to make up new brackets to suit the chassis or mod the chassis and try to strengthen it and tie it into the front chassis a bit better while I am there.
But at least its in and looking reasonable :
And just to check I got it central in the wheel arch I stuck a rim on it. It sits a tiny bit further forward than backwards but I think this is probably a good thing. The tyres on these rims are 215/60/16 which are Outback sized - will eventually be running something like 215/40/16 which are nearly 90mm smaller in diameter so there will be heaps of clearance and heaps of room to get it real low......
