67 commando 273 issue

So I picked up the suggested edelbrock 9266 spacer and the bolt pattern on my AFB and factory intake are quite different.
I could maybe butcher this spacer but it won’t be ideal just the way the correct gasket overlaps the 9266 for comparison.
Am I missing something?

My buddy who is a retired mechanic said to just make one out of 1/2” plywood as that is the way they used to do it all the time in the old days, but I’m a little leery about putting a flammable item where all of the fuel and air comes together.
