Just finished a FH restore,my second swap, first was a TOTAN. FH seemed more complicated,but,you can do it. Take extra pictures of the trough switch area, seemed tedious. I did the swap side by side on the floor. Don't get in a hurry, lots of patience. There is a thread here with a Tnuts map for a FH, very helpful,you need it. As stated, when you are done, lot of tweaking. I also did my first full cabinet decals on this, what a job. Mirco playfield was easy, expect to have to shim the shooters or playfield supports. Didn't have that problem on a CPR on TOTAN. Good overall quality on the Mirco. You will be proud of it.
