The front-most bolt is the easiest. Seriously, run out to the nearest store to get some Vise-grips or some other knock off (if you already don't have one-- lost mine -- heheh -- around a 6" long or greater handle), and get that lower, far back, bolt broken off the manifold (not literally, just loosened). It does come off. The one diagonally is also on the manifold. All told, four bolts; the long ones P2R provides works fine to replace with the 13mm socket. Loosen it slowly a few turns at a time; you'll be able to use your fingers at some point.
Here's the generic vise on the first (easy) bolt:
uh so my bolt doesn't come off -_- is there other way i can take them off?
and do you just screw it before you put the spacere or what?
