Thanks Elm, dead right. That's what I get for trying to google stuff while pretending to be gainfully employed 
Looks like the AIM-7 is carried on pylons 2 & 7 (1 & 11 being the wingtip launchers) on the superhornet.
The AIM-7 needs a LAU-115 launcher, Wolfpak make them, not sure who else.

Or you could try to scratch them. Maybe from the launcher that the kit includes for the AIM-120? Here's a couple of pics

Good luck malish85 and post pics 
Also, out of interest, the F-15 did carry a mix of AIM-7's and -120's in combat for a number of reasons by the look of things.

Maybe the Hornet, in one of its many variations has too. Could be an interesting loadout...
