Are the emblem areas on the ground effect rocker panels for the 91-92 gfx all the same ? For example, will a Z28 rocker emblem, or an RS rocker emblem fit the same gfx panel, or will Z28 rocker panels be required to use a Z28 rocker emblem ?

I did a search, but didn't find this specific question addressed.

Thanks in advance for any input.

 

You shouldn't have a problem, they are all the same size, I can tell you this because I took me IROC-Z Emblems off my 1985 rocker panels and pput them on the new 91-92 rocker panels with no problems at all.
Now I got rid of the plastic Emblems and went with these...
