so i just picked up an 89 IROC cheap off a guy who had just swapped in a 350. he wasnt quite finished and had to get rid of it due to personal reasons. well i need a fuel pump for it, so i picked up a holley "red" fuel pump. perfect for what i need, but i went to install it yesterday and discovered it had self tapping bolts that came with it. my question is, weather i can guy just buy regular bolts, and install it with them, or do they require the self tapping? im confused about this so anyone with experience with this installation please feel free to chime in about your installation. thanks in advance for the help!
