they are the stock ones. I just got a 5/16" bolt and cut it down on each side.Cost .50 for the 2 bolts. You have to cut the bolt to the right length to where the light is where you want it when tight. trial and error. Red Loc=tite it.

I just answered U ?'s in the other so I hope they help.

I'll add that the BEST mod I done was the Cams.

Read the other info I gave ya also but IMO the best bang for the money was adding the cams, STG1 will give U 5% -at most 10% , but the cams adde another 15% -20 more than just the stg1 did.
A lot more fun factor with them plus I ended up getting 2-3 more MPG which don't hurt any these days.
