Does the engine you are using have a rear mounted carb? If so, will you have to cut an opening in the firewall for it? You could use that opening to install your blind nuts. But, if you don't need to cut the firewall to clear for the carburetor it wouldn't help. How are you going to run your throttle hookup? I think you may have to open up the sheeting.
