Looking to build Hornet w/8 AMRAAM missiles. I guess I’ll need to modify the pylons. Will aftermarket pylons take care of this? What do I need to do?
Which scale?
1/48 scale.
Hasegawa Aircraft Wepons Set E

I’m not sure it’s the pylons you need so much as the lauch rails for the missiles, the LAU-127. It looks like the Hasegawa set Hermann mentioned does include those.

Yep, you need the LAU-115B/A with dual LAU-127s, as provided in the Hase weapons kit.
