Building up on a new Uni casing & Mag housing and had to pack the Mag housing out a bit to get crank gap right -Anyhow the 3 nuts holding the Mag housing are about 1 mm from being flush with top of the nut...is this a problem? e.g. Get slightly longer studs??
I did think about a dab of thread lock on the 3 studs and torqued up the nuts.
Advise welcome cheers
