Yer right he needed Mr Gasket part #1932 same link.
That will not bolt ( #1932 ) on unless you drill & counter sink & buy flush mount screws. Even then, not too sure it will work because it has a spread bore clearance pattern ( large sencondaries) & not enough meat for the mounting holes.
It's been so long since I ran a spread bore adaptor, I know I had to modify it to use one.
I am talking about using just one adaptor plate.
Not using his adaptor plate & stacking another adaptor plate on top. that will equal less hood clearance,,, if that is an issue?
TwoFiftyShifter, what kind of vehicle is this going on?
