Ya gotta ditch that cheep plastic intake spacer. I see them on everything now. They all break or crack especially the bolt holes break off like yours did.
Buy some Phenolic board sheet and make your own intake spacer. It comes in different thicknesses. AMAZON
Phenolic board I'm talking about is Tan in color and it's layered like plywood But It's not plywood
Reminds me of the stuff electrical board is made out of
Phenolic board is what car guys use for their Hot Rod intake spacers.
I use Phenolic board spacer on my Whizzer M/B intake - Phenolic board is also a heat insulator to keep the heat away from the carb
If your not sure what to buy I'll look up a link for ya
