I would keep the original.
But this is a hobby for most of us, so if you love the thrill of PF swap...swap and sell that nice original.
You will recoup most of your cost of the new one.
Sometimes we all get caught up in the "value" of it all and forget the fun of it all.
I really enjoyed my PF swap days but that has come and gone. That is one nice PF and I would just rebuild it to show it off. New PFs area a pain t-nutting, GI wiring, pre-drilling and are rarely smooth unless cleared by a professional.
