Top right proving difficult
6ac Tool needing caution given back, to overcome anxiety (7) I have ??NG?A?
12ac Racer speeding round main road - it's deadly (6) I have ?AR??T
The N in 6 and the T in 12 depend on 7dn being NATASHA (Clue - it's not applicable to keep working on remains, for a girl)
As usual, all help appreciated.
