Stupid simple mirror nut question
Can't believe I'm asking a question about mirror nuts but does anyone know the part no. for the longer OEM acorn nuts? I just got a replacement set of short-stem mirrors for my 23 Heritage and the acorn nuts they came with are too short. The fiche says 7331 but not sure if that's the short or long one.
I know I could add a stack of washers or a 5/16" nut but I want to keep it stock and here in the UK we don't have many hardware stores I can just walk into and find similar from.
Thanks!

Maybe a chrome spacer
Maybe a pic of the mirrors or a link to them could help someone here to help you.

Thanks yeah theyre just the standard HD short stem mirrors, sold in a pair.
I must have missed the mirrors when cleaning the bike this Winter as mine got pitted and the nuts rusted, so I replaced them.
The mirrors are identical but the acorn nut is about 1/2 shorter with the new pair than the one that came with the bike so Im looking for the p/n for the longer nut.

Failing that Ill just grind the excess threads off and use the shorter nuts that came with the new mirrors.

Different year bike. So this is just for info in case it helps your situation if the one you ordered does not work out.
But I just did a mod that took the blinkers off the bars control mounts. The left side had an adaptor for the blinker / mirror mount and no acorn nut for that side as the blinker went on the fitting.
I bought a 5/16" x 24T acorn nut at our hardware store. Very, very close to the OEM acorn in appearance of the right-side mirror stem. I had to trim a slight 1/8" to a 1/4" off the left side mirror stalk threads so the nut does not bottom.
Easy fix. Looks factory and was $2.

Did the mirrors not come with small chrome spacer rings? They either raise the stem a bit higher or they go on the bottom to take up the space to allow the acorn to fit properly.

Time to get the grinder out I reckon. 1/2" off the stem thread and it's sorted.
