Question about versions of F-4 having slats or not

We know that all F-4E can receive the TO.566 providing manoeuvring slats. (and that F-4C and D can’t)

As F-4F and F-4G are directly derived from F-4E, I assume they also have manoeuvring slats (at delivery or later by retrofit), am I right ?

What about US NAVY F-4J ? (that is clerly not derived from F-4E without internal gun), and its modernized version (F-4S) ?

Last, what about the UK F-4K and M (FG-1 and FGR-2) with Spey engine ? that seems more derived from F-4J than from F-4E

Thanks in advance for you help
