1) You got an amazing deal on rotors, pads, lines, fluid, and the SMY cluster! Wow! :bow: You're going to love the SMY cluster! I have it and it looks like the car came with it out of the factory. Very subtle, non-intrusive, and positioned ina great spot for visibility.
2) Dealerships use an automated motored device that essentially does everything for you in terms of bleeding the brakes. I've seen it done on other cars, but never had it done on mine.

4) I'm going to recommend you always use anti-seize. You may not need it, but I'd rather be safe than sorry. I'm not sure how the VA models are, but GD and GR are both prone to seizing. Just use the anti-seize for peace of mind, and it's very inexpensive.
Please post pictures when you swap everything! :tup:
