I'm after some advice as usual, started to fit uprated diff mount today and have ran into a couple of problems, the first one being that the bolts are touching the ARB, I know that this is a common problem so I am going to source some new countersunk bolts and then countersink the allu back plate to clear ARB (not a major task).

As you can see from the picture as I jack up the diff the mount is not sitting flat with the floor section cross-member, the two foremost fixings (nearest the diff) touch first leaving a 5mm gap at the back of the fixing plate, I have tried putting the old one back on to see if it sits flat once jacked up into position, and it does but bearing in mind that the ford item is also a lot more flexible.





So my Questions are:
1, would it be OK to just bolt it up, is the billet alloy strong enough to do this without bending it I don't want to crack it.

2, would loosening the diff bolts to sub-frame help re-aline it or is there no slack there on the fixings.

3, would it be alright to put a 1 or 2mm shim/washer between the diff and the mount bottom fixing bolt which would probably be enough to close the 5mm gap up.

4, Do you still torque the bolts up to the ford specification or will this split the alloy

Sorry if it's all a bit long winded, but is it just me that seems to get problems with everything that I buy or try to do on these cars that we can,t seem to grow out of.
