In the 345, almost certainly, and almost certainly 7.4 to 7.6 KOhms' worth of wire, as pre-T-Tops were wound very neatly and consistently. In the SG, with its Pat. No. pickups, also almost certainly A5 as well...though there was still some significant wind variation in those. In the Strat, almost certainly A5's.
But remember that in the Sticky Fingers "era," he mainly used amps with a ton of headroom – high wattage Fenders a lot of the time to record, and high wattage Ampegs to tour (as well as in the studio). Using a Deluxe, which is a dirtier amp, you want less pickup output in order to cop the same tones he got from his high headroom amps. So I would aim for lower output pickups, like you tend to get with the lower end of PAF winds combined with relatively weak A2 mags.
My vote is still Seths...and if not, then A2Ps, not '59's. '59's are quite strong for PAF-style pickups. That can drive a 65 or 100 watt amp really nicely. But it might push a Deluxe Reverb too hard for what you are after.
As a somewhat related sidenote, purchase orders from the PAF era of Gibson show that they ordered several different types of alnico bar magnets (alnico 2, 4, and 5 IIRC, and maybe even alnico 3), which were used to make both humbuckers and P90's. This adds even more inconsistency to PAF specs that are already highly inconsistent due to wide variations in winds. But here's the thing: 70% of the bar magnets Gibson purchased were alnico 4, a type that is very rarely used in PAF reproductions. This is more a point of trivia than a recommendation, though. I still vote Seths or A2Ps for that amp.
