What colour were the ends Rob? where they poked through into the front boot space.
I guess the weathering would be minimal and would be pretty original colour seeing as your car has survived so well. being only 43years old and all:roll:
Zinc to my knowledge is only ever a grey/dark grey.
I'm not sure what the original finish would have been, mine were very black in colour. similatr to 'oil blacking' colour, this is a protective coating you could achieve by heating the bolts up to a dull blue/grey colour (not red/orange hot)and then quench in oil, remove straight away, wipe of excess leaving a black protective finish.
(cheap but effective)
