There's a pad under each of the bottom BAE barrels. You can ISO it no problem.
That sounds great, would you explain to me how to do it, just put a spring there?
You have to open it up and move the switches to the proper barrels (i.e. the spring/pivot plate assemblies).
Take a look at the layout on an F122 as a guide.
I'll also add that you're going to see a lot of warnings about how hard it is to reassemble everything, and warnings about disintegrating foam.
If you're just doing a single move of a spring and flipper, its much easier on a AT than it is on a 122. Unless the foam is totally destroyed you won't really be touching it enough to worry about it falling apart. Also, closing up an AT can be done without needing any extra tools if you're a bit careful (and have big hands).
Watch out for the spacebar. It doesn't come off like a normal key, so don't actually remove the spacebar before you take everything apart, but definitely take off the other keys. Once you open it all up, this will make much more sense.
