Hi All, '77 308 GTB 21819 with Euro headers, Tubi exhaust and no emissions equipment. The headers have a bung on each pipe and are capped with a bolt and a washer. Looks like I'm missing one. Either I missed it and it's always been missing (I doubt it) or it worked itself loose (also hard to believe). But either way, My #2 pipe is missing the cap-bolt and washer. Looking at Ricambi it seems like this is the p/n, but it is not stocked. P/N: 103748 CAP Anyone know if this is the correct p/n and what the thread size is? Wondering if this is something I can find locally. Sorry for no photo. I thought I snapped a photo last night, but I guess not. I'll post a photo when I get home this afternoon. Thanks! Mark
The part you cite is a plug on the exhaust analyzer tube for US cars only and is dramatically smaller. Leave looking up parts to the parts guys. You will get the right part far more often. What you probably need is a 110860. Pretty sure its a 10 x 1.25 and they are stainless. Any Ferrari shop should have some laying around.
Here is a photo since I said I would upload. And I had the wrong cyl. Not that it matters. Image Unavailable, Please Login Sent from my iPhone using FerrariChat
Sheesh. I still don’t know how I missed that. I’m just shaking my head. I can’t see the 5-8 until I lift it. The other three are tight. Sent from my iPhone using FerrariChat
Looks like the ones that are in there were Frankenstein’d. They are standard bolts that were cut down to just a few threads. All oxidized badly also. I broke another one loose with little effort and it came completely out with maybe [emoji637]/[emoji638] turn. I’ll be ordering a whole set with washers now. @Rifledriver - Thanks.

On my QV these plugs have a locking tab ro keep them from getting loose. Not sure if these also apply to your car, but worth checking. Picture from superformance. Image Unavailable, Please Login
I believe they do. I ordered them and the copper washers as well. My car is missing those tabs and copper washers. Thanks for the photo. I ordered from Ricambi and their photo wasn’t shown. Sent from my iPhone using FerrariChat
