I wish I would have got a new disconnector and strut too. I hate beating out the old parts to assemble with a new hammer. Then when I swapped the hammer back to OEM I had to beat it apart again.
Also, I wish I would have ordered a spare lifter spring. I haven't seen it in 6 months. I didn't even disassemble my sear cage (decocker) but it slipped out while transferring the slave pin. I think the lifter is the same, safety / decocker. So I bought a $3 spring and $8 shipping and $100 humility. They say humility is good but I digress.
