Smallest radar to support Aim-7 Sparrow AAM?

OK, revisiting this post in the hope that we might have more info and more substantiated answers with time

Came across this interesting article:

As my original question pertained to my want and need to fit a radar supporting Aim-7 Sparrow AAM to the Vought V-383 Crusader, I find it intriguing that the manufacturers brocher clear says that ‘four Sparrow missiles’ could be carried by the V-383 and smaller and lighter V-384, I again can’t help but wonder if it only required a CW Illuminator, and where would this have gone?

Looking at these fantastic insightful drawings of the original V-383 and V384, would such a CW Illuminator have been carried in place of one of the rocket packs?
Also, the four under-wing hardpionts/pylons (two under each wing), were these two hardpoint totally eliminated from the ‘production standard’ F-8A Crusader?
