So is it LS swapped? Cause that's what a 5.3 is. And LS platform engine doesn't have a distributor, so no cap or rotor.
'97 1500 would have a 4.3 V6 or a 5.0 or 5.7 V8. Best replacement plugs are new ones of the same brand and part number as what came originally. My '97 one ton pickup with a 5.7 had AC #41-993 plugs in it from the factory, and that's what I put in to replace them. Those are iridium, and $7 apiece from Rock Auto. They specify a .045" gap; they were pretty close but I checked them to be sure, with a gap gauge.
For the cap and rotor, I got those from Rock Auto as well, the United Motor Products vented cap and rotor set. They're blue and have brass contacts which are much better than the aluminum ones cheaper caps come with.

If 5.0 or 5.7 then my 2 cents-
