Thank all, mine has the Ford MT-75 box (2010), its heavier than the Mazda box and the relief each side of the cross member is even less.
I think like you Rog I'll tap the cross member; maybe see if I can get half nuts on to act as locknuts if there's clearance or just a dot of lock tight if not!
If I fit it, it will definitely have to be modified either by opening out the fold angles which I fear may distort the heavy plate at the welds and cause damage or, rather relieve the plate at the contact points of the gearbox casing with some added clearance as well.
My real reason for the post was to find out if anyone with my configuration of engine and gearbox in a plus 4 had fitted one and how it fitted their car. also what there clearance between G/box and crossmember was.
I was thinking of maybe spacing the rear mount of the gearbox by a few MM's to give me some clearance at this point as mine only has about 1-2mm static and you can see evidence of contact in use. I can't see that the diff to propshaft or diff to G/box angle would cause a problem here as the minute angle change would be taken up by the U-J's and sliding joint. I don't think you could even measure the angle difference it would create and when you look at the chassis itself and the crossmember's accuracy I'm sure they all vary slightly in position. Yet all the rear mount spacers will no doubt be the same! As a last addition, the cross member shows no damage or deviation in it's construction or fitting no do the chassis rails which are straight and true.
Again any thoughts would be gratefully received. I have been an automotive R+D engineer for my sins but I don't think you can really apply any construction and use regs to a Morgan chassis, well not within any real tollerances anyway!
