Spark plug questions????

[tntcorvette]

I am running a/c delco fr3ls plugs (rec. by afr) and per msd I need to step down 1 heat range with the use of the 6A.

I cant find any FR2LS plugs, which is one plug colder.

Anyone know where I can find some on the internet? Or better yet, anyone know of a comparable plug, that is not EXPENSIVE? I.E. $5 a plug or such?
