Bought a Yamaha! Thanks yall!

Hi, I'm a happy owner of a PX-130 which is going to my daughter now, so I'm looking for another Privia! I've been searching for a digital piano and found a couple local used options that might let me save a bit of $ (or might be a big headache haha, which is why I'm asking here on the forum!). Two of them are "integrated wooden stand and pedals" models, PX-860 and PX-770, which are missing the stand and the pedals. For my space I actually prefer no stand, but need the pedals! So my question is, do these pianos electrically require the exact pedal units they came with, or could I plug in say, an SP-33 and have it work? Appreciate any info/leads! I'm usually really good at googling stuff and not asking repeat questions, but couldn't find this info online.
