[TR] Thread size for TR6 instruments?

[Steve Smith]

Hi all

I hit a sped bump putting my gauges back in my car this morning. About half of the knurled nuts won't thread back on so either they were cross threaded previously (or I just cross threaded them!) or some are a different thread and I've mixed them up.  

Is it possible that some are UNF and some are other (BSF or Whitworth)?  If that isn't the case I can run a die down the posts - it appears to be 8-32, can someone conform this for me before I ruin my instruments?

Thanks as alweays for all the help & advice as I bring this thing back to life.

Steve
