You made the right decision. I have done a PF swap on AFM twice now. It's intimidating the first time; however, there are some very solid guides on here to help you. My thread is ok - and I mean just ok - for the swap I just completed in Dec 2018:

Fellow pinsider, mof did a FAR superior PF swap guide which can be viewed here: https://pinside.com/pinball/forum/topic/playfield-swap-guide
I am so hungry to do Scared Stiff. After doing AFM, I wouldn't even begin to hesitate. You'll be SO happy when it's done. Don't be afraid to ask questions here. Good luck!!!
