rdrp brass bulkhead help
 

Just received this from mb today. It is a multi option 25°/30° inserts but ive no idea which way to put the inserts...they aren't marked at all and there's no instructions. basically 4 inserts. All have a notch at the bottom...Therefore you put them all at the bottom...all at the top or a mixture of rear bottom front top and vice versa...Please help :( my setting my car normally has is 30°

Notch up at the front notch down at the rear is one angle, notch down at the front notch up at the rear is the other, can't remember which way without looking, but it's obvious! if you set one one-way and the other the other off the car just with the pin's in there's a blatant difference, both notches up or down is a none event the hinge pins won't go through.
