Thread: Twice my age, crosseyed and can't hold her fluids in but ain't she sweet

46mm is the closest assuming the chart I have is accurate

I know it's 1 11/16" (1.688")

See the chart here

Hi Lou,
Sorry I didn't see your post.
It measures out to being 42 and a bit mm if I remember correctly. Drifter is most likely correct about the 46 being closest metric size.

The 1 11/16" is not a tight fit, you could get away with rounding down to the nearest metric size.
Like you said, 42mm would probably be the best bet. I doubt you'll have much trouble getting a socket in that size.

42 is too small.........

Must be very close though. 1 11/16" converts to 42.8mm (or so) and I know for a fact that 1 11/16" fits the nut fairly loose.

That's the most beautiful thing I have ever seen....

Hey Johnno,
Thanks for that Its the sort of comment that makes me want to get back into it.

Then again, it could be because I broke the County that i'm pushing ahead with Dirty Mary (the Black Maria)

Yesterday I torqued up the head, this evening i've fitted the manifolds, oil pressure and temp senders and carby. I'm about to get stuck into the radiator. All going well I should be able to get some oil, water, fuel and spark into her and wake the neighbours tomorrow.


Oops, is that the time, better get back into it!
