I presume, from his comment, jonnyangel04 has removed and reinstalled the S/C from the M112K already. The upper spacers (e.g. LET) are relatively easy - but still a bit of a PITA because of how they change the angle as you're trying to seat the intake plenums.

My concern with the lower ones is simply the relative complexity/effort in removal of the S/C, and in making sure everything's reinstalled correctly. How difficult was that, jonnyangel04? Thanks.
