OK, totally stumped on these last two!
6a. Rejected trash can head to special tips (4). N--- or possibly N-B-
7d. I won't tollerate some races run in short sections (5) --G-T. Could be BIGOT, but I can't see the parsing.
As always, any help gratefully received.

7 Go, run, inside Bit(s), short sections.
