what phenolic spacer for eddy carb to stock 273 intake?

thanks. car had been put off for a while and im planning on a intake change after new years. was thinking of trying a spacer for temporary help. being the intake is stock and the studs go thru the holes closest to the inside of the carb what spacer do i need? i have seen some but the holes dont line up with my studs thanks.


Dad got one from Edelbrock, cant remember the part #. Same problem with stud holes not mounting up, he drilled them out to make them fit. It wasnt $50 though, Im thinking $30??
