I'll look for the sealant for the tail lights, I need to get some supplies in the morning for an oil change on the tundra.

For the roundel I'll probably go without the adhesiuve strip, might just put a dab of the butyl.

Then I need to figure out how to swap the airsprings....a cinch on the e53. Looks a tad more involved on the e70.

Thanks guys, great knowledge.
