Thanks for the advice, I realized it was really just one of the o-rings that had been fighting me with a vengeance so I pulled it out and was going to try my last spare with some grease like you mentioned and noticed that the offending o-ring was swollen much larger than the others/new one. Either it absorbed something I put on it trying to lube it up or it was just a bad o-ring but after swapping in the new one and with a tiny bit of lube it went on much easier.

FYI for the future folks attempting this DIY, get at least 5 (maybe 6) of those o-rings to replace the 4 squashed/dried out ones in there and check for consistency between the new ones since it's a tight fit.
