1978 DT175 Flywheel/rotor nut thread was created by MikeK-uk

Good day all,
I’ve got my NOS source coil (previous thread refers) and want to fit it.
Before I hurt myself or break something… the 19mm flywheel/rotor nut… left or right hand thread?!
Many thanks,
Mike

P.S. Threads for the proper puller are 27 x 1.0 LH.  Very common tool.. don't try to pull flywheel without the correct puller.
