6112 install…. Bump stop question

So I just wrapped up my 6112 install 1.9 setting.

Installing the bump stop spacers and of course the last one snapped the stud…. FML

so the question is since it was the rear position and that is where the Durobumps go “if” I decided to up grade would I still put the supplied spacer behind the durobumps?

I have read the compress to the same height as stock so it would stand to reason that I should have the spacers installed all 4 even if I up grade to durostops. Or so I just leave the spacers on the front 2 stops and run durobumps in the back with out the spacer .


Thanks

 

Second question any one have the part number of the factory front bump stops? They visually look the same front and back

 

what year?
