Hi all,
We are doing a Heystee front disc brake mod on a 1983 series 3.
The mod means there will not be a drum back plate fitted.
So the bolts will go directly through the stub axle.
This will make the bolts slightly longer going into the housing.
Being as I do not have any bolts yet or know the thickness of the drum
can any one advise me if the current bolts (237339) and lockplates are suitable.

Thanks Peter and James
ps. This is an abandoned project by my eldest son from 4 years ago.

EDIT....Also the torque for the bolts please.
