Hi guys,
Prompted by the wanted post and same on the mk1 forum, I had a look at what I had.
I knew I didn't have the originals, and had bought two of the reproductions.
The repros don't hold the air box tight even after running a die down the elbow thread without cutting more thread, and don't look like pictures of the originals.
I have three of the longer ones for the single air boxes I can shorten in the lathe and re tap.
Can anybody help me with the dimensions.
Thanks in advance
Stewart

Hello Stewart,

I gave it a go for you. I measured one I've got here and I get 30mm from under the head to the end of the tube. The length of the thread measured 16mm

Regards,
Glen

Here’s some we prepared earlier

It was one of our reoccurring conversations in our local mini group for a while and it’s burned in my brain

Thanks Guys, I had read the topic Timmy posted but to be honest I was still confused as to which of those pictured referred to a 1966 cooper S.
Apologies if I've been obtuse, a lot going on in my aging brain at the moment.
Thanks Stewart

I believe the 1966 S should have the one on the left

Left: Shank = 30mm / Diameter = 8.8mm

Thanks Timmy I'll compare it with the long ones I have.
