One of the best junkyards...

...is in Alpharetta, GA.  It's called English Car Spares, and they still 
have a lot of original Lucas/BMC/Smiths parts kicking around.

When I was there last week, oddities included:

complete head/tail/park light assemblies in their boxes
timing covers
misc engine parts
a factory-equip. '67 BGT "deluxe" steering wheel in wood.

I think they ship, if anybody's interested.
