Hi guys.

I've got a problem . I removed the exhaust manifold and lost one of the nuts that fix the ex. manifold (with the 3 screws). I'll show you a picture of it.

The car is a Santana 88 (i'm from Spain) and suppose that the nuts are not metrics (they are made in inches) because it was imposible to find another one.

Does anybody knows exactly the size and kind of this nuts???.

Thanks for your effort

5/16" UNF Try and use brass nuts to prevent seizing

Thank you .

I found that information in google but i was not sure if true, because i went to the hardware store, gave me 5/16" nuts and was imposible to twist it on the ex. manifold stud. Probably they weren't UNF.

5/16? You sure? 7/16, I would have thought if its imperial.
Also if you tried m10 nuts, did you try m10 coarse or fine cos it will be coarse if metric. (which I would have expected being a Santana)

Unscrew the studs, then run an M10 tap down and through the holes and use some M10 studding with brass nuts ... Problem solved!

Yep. Exactly what scrappyloz and I did on my conversion. Why they went with those studs got only knows
