Yes guys sorry my bad, it’s a Schaller signum I will correct .
However to reiterate if you are using it as a replacement on the Bernie . It’s the metric version to fit the posts . The metric studs supplied fit the bushings thread but not the depth they are too short !
Only solution is to take out the existing bushings drill the hole to the length of the stud ( around 5 5mm) and then drop back in the existing bushings replace the existing bushings which are chrome but not really visible unless you go looking for them .
On the you tube video where the guy demonstrates the signum replacement on a core 245. The new pushing drop straight in and no modification or drilling is required as both the thread and diameter of the bushing are the same . It’s in practise an easy fix on the SE just make sure you mark your drill bit with tape so you don’t go through the body and also the earth wire is in the bottom bushing hole so drill marginally ithe diameter of the bolt not the bushing as you are now drilling for the bolt only which is a smaller diameter than the bushing hole.
