The EA82 engineers slipped up and used the same centre-to-centre measure for the pressed metal trans tunnel brace as the EA81 auto trans cross member mounting points

So....why not? I may adapt my 4WD as a FWD yoke holder when I pull the tailshaft trick

So you were able to bolt in an EA81 crossemember onto your EA82, but that the new part doesn't support anything?  That would be pretty cool, a low buck chassis stiffener!

I haven't tried your suggestion. This is EA82 part into EA81 body. Only uses half the four bolt holes, so not much of a chassis stiffener but I guess it leaves things open for modification to add more holes, crush tubes and bolts through to the floor. Correct at this time the EA82 chassis stiffener holds nothing at all BUT it has got it off the to do list and to do shelf even though it advanced to the passengers footwell   and as I said the intention is to add to it to stop a tailshaft yoke from popping out while in weight saving/friction reducing/fuel economy boost FWD mode - ie no tailshaft, rear diff, axles of hangers
