MSD Cap / Rotor O-ring installation...
Am I right in the following?
The square O-ring goes on the original opti base.. even though it's a little loose around the lip, it seems to fit correctly once the isolator is set on.
Then one of the rounded regular o-rings goes around the isolator and the cap sits on that.
The last o-ring isn't used.
Right?
All done.. goes back on tomorrow. Had a bit of a high RPM miss and my stock rotor had some flex in it.
