I have a weird problem, my VAB and SPH don't have the concrete base and pylon in the menu. I realised this after updating KIS and KAS, but reverting didn't fix the issue and I seem to still have all other parts. Saved ships that had them in inventory still do, can be launched and then pylons placed as expected. I'm thinking that its a mod conflict but given my game has a 10min load time, posting here will hopefully be faster given the 50ish mods. Lucky they are listed in the OSE workshop build menu, so I can work around it for now.
