Looks great man!
as far as low profile hereare the ones i purchased as I ran into the same issue. Your not gonna find a halogen that matches the color so your going to need to wire in a set of resistors with the led bulbs to stop the hyper flash. Bottom line is with all the work you've already done, wiring in the resistors will be a walk in the park.

resistors:
if you google a 50w 60ohm resistor you will find tons. That's what i have used and they work, im sure there are other options out there.
