engine mounts

[old_bill]

I am now ready to fabricate the engine mounts for my 1.8 cvh.
Following the book instructions I have sat the chassis on 25mm tube and have positioned the engine in the engine bay (where else ). I have also mounted the diff. My problem is when I get the engine positioned horizontally the distance from ground to the centre of the gearbox shaft is higher than that to the centre of the diff coupling. I have not yet modified the sump. Should the engine be at an angle from fron to back? Any advice would be welcome.
