Engine mount specs?

[Rex Delay]

Need to double nut my motor mounts. Tightened the existing single nuts with a 24mm wrench. Without taking one off, does anyone know the specs for the nuts? Diameter, thread etc?

Standard metric bolt size for a 24mm wrench is a 16mm bolt, and standard threading is 16x2 (16mm diameter x 2mm pitch). If your motor mount bolts are standard then that should be the nut you need....
