Autoexe strut brace

I have procured myself a 3 point AutoEXE strutbrace out of a NB,Has anyone fitted one to a NA?,I know it will fit,did a sort of test fit today,My main concern is how you got on with bolting down the rear plate in the scuttle panel area.
There is no way of bolting it down nicly without taking the dash,Isa as simple and nasty as self tappers?.
The brace came in from Japan in a shipment so don't know how it was done,I can't even find the brace on Autoexe's web site,Photo's of how someone has done it would be nice.

I reckon we could do with a Body brace/Strut Brace thread ,Lots of different options out there.
