I just picked up a nice set of hood blisters for my 91 RS. I have been told that they go in the same locations as the IROC louvers, but I want to be sure. Also, does anyone know if there is a template that someone has made around this site, or elsewhere for locating the exact locations for the holes. I'm scared to death to put drill holes in the wrong location. Thanks guys

well if you have a RS you should have a falt hood and factory hood blisters wont work cause z28 hoods are indented for them to fit in, what you need is the ones that hawks makes for flat hoods

Exactly
