^its one of the long 10mm bolts that seal the timing chain area of the head. To get it in, u gotta pull the cam gear off. The FWD SR has a different bolt setup for the timing chain area. They're on the outside. You might be able to score one at ace hardware, just make sure it's a high grade bolt. Like grade 10 or similar. To get the right size/thread take the other 10mm out that's inside the timing chain area.
