yes longer bolts is an option now that the problem has been identified. But at the end of the day it's a low end knock off that sells for $55 on Rock Auto and the one review I can find on it says even after buying longer bolts, they got vibrations from it that they never had from the MB unit.

So if I have to put effort it to make it work, I'd rather at least attempt to get a good used MB part first.
