I made a pair for my car. The studs on the carb elbows were threaded 1/4-20 (UNC) so I tapped both ends of pieces of 1/2" diameter aluminum for that size. I used Loctite to bond a long grub screw in one end, dropped on a washer and followed it with a wing nut. They don't look like the one piece original but they are very functional. Mine look like "long eared" versions of those above shown by Kees.

I'm blown away (still) that nobody remakes this part in any big quantity. Think of all the other Mini-specific parts that are remade, and nobody remakes a wing nut for an air filter?

(Rich/MiniSpares, is there a particular reason for this? I'd imagine you would sell quite a lot of these.)

The thing I had been pondering for quite some time was could the later nuts be converted to suit the twin SU box ?
This has encouraged me finally to have a look and it’s a NO
The wings are totally different .
Shame as I’ve collected a few now with this in mind :(

I've stripped the thread in one of my originals and thought that I'd bore out and insert a threaded brass(?) insert. But it's the bloody thread that has beaten me - so far!

Just re-read Dougs thread. Is that what they are Doug, 1/4UNC?

Personally Peter I would insert aly back in there , it gets rather warm in there so would expect the aly to expand and contract quicker than the brass and in time come loose.
I would tap it M8 1/2 inch deep and forcibly wind an aly stud in .
Re end it back up and drill and tap 1/4-20.
Maybe a bit of green loctite and jobs a goodun
Only my opinion ;)
