There is no tape on modern Stern rails, just bolts and screws.
I wish they would include the extra 6 screws you need with the rails but they don't so be sure to order those.

If you put a slight inward twist to them before installing you can go without the extra screws but I put them in since I won't be going back to the old style rails anyway.
I bought a NIB T3 and swapped out the rails so it would match the other games in the row.
On games I have sold I try to give the old style rails to the new owner but they never want them so I have about 6 sets.
If you do go back to the old style you will have a mark where the lolipops were.

If you pull the flipper buttons and mist the area with flat black and that bit by the corner the new rails look much better when you install them.
