Default Strong Diesel smell and Injector Seals

So after tons of searching and reading and not finding much, I've solved 2 issues at once.
I have been developing a 'tick' on my q7 TDi and a strong fuel odor in the cab anytime I'm not moving.

I've traced it down to bad injector seals (just one, actually).

I'm planning on replacing all seals (rubber and copper) and have 2 questions for those with experience.
Where did you get the seal kit?
Also, is 200k a good time to replace the injectors, or should I just run them till they give up?

Malone stage 2 and dpf/scr delete.
