[Healeys] Exhaust hangers

[Hank Leach]

Curt-absolutely, I'm glad that I had them for my 100 and they are on
the car #588 October 22,1953-not too many UNF hardware items on this
car. Regards, Hank

 Hank 
 Thanks! Very cool photo, may we use this for the AH Concours
Guidelines? 
 No one can tell just when the "U" bracket threads changed.  
 Many Whitworth fasteners on the late BN1s and BN2s were changed over
to UNF in late '55 nad '56. Most of these changes were documented in
the factory parts manual and service bulletins while some were not
documented at all. Like Hank stated, when the parts bin ran out, new
items were often sourced and installed, and not necessarily
documented. 
 Until we can confirm that were UNF threaded "U" brackets used on
later 100s in lieu of the BSF ones, then the assumption has to be that
they were used until the end of BN2 production. So, if anyone out
there has an original "U" clamp from a late BN1 or BN2 with UNF
threads, please submit documentation to Michael Salter and me so that
we can update the Concours Guidelines. 
 Cheers,

  Ok, as long as we are showing clamps, here is my NOS exhaust bracket
set. It was still wrapped in this photo, but as Curt says- its British
thread-probably until mid 1954 when they tried to unify or whenever
the bin holding exhaust brackets ran out and they refilled it.
Whichever came first. They did not throw any away in lieu of unified
replacements. 
 Likely, Michael's new set will be UNF as they are not making any
early parts for "purists"-same holds true on the rear gearbox mounts
and other items as well. Hank
