Hi  Listers,
Quick one.
What is the thread size of the bolts for pillar  of  windscreen to body on 
a 
'62 sprite?
My best test is the bolts  are 5/16" but not clear if they are UNF or BSF. 
My thread gauges tend to  tell me they are 24's but a 5/16 - 24 die does 
not 
work well on a removed  bolt.

UNF = unified fine  60 degree inc angle and 24 TPI
BSF =  British Standard fine  55 degree inc angle and 22  TPI
