I installed BBK lt's about a month ago and there was a nut I couldn't put onto the passenger side header that is closest to where the passenger sits. We had to keep the stock bolt that sticks out from the stock manifold for that perticular one because we couldn't get a locking bolt in that little area. For the past month I've been driving around w/ a nut missing on that one bolt. Well I was messing around under the hood and I figured out I could get to it from the top of the engine. My problem is that I'm not sure what size nut fits on that bolt. I was going to go and buy a couple of them and see which one fit but if by any chance anyone knows please let me know. I can only feel it with my hand and it would be hard to measure it w/ a tool because of the small amount of room. Please let me know if you happen to know the size of this bolt.
