Thanks Natee.
I needed the speedometer, but while browsing your link for the tach, I located a speedometer from another merchant. Not cheap, though slightly less expensive than quotes from dealers and more importantly, in stock.
For anyone that needs a speedo, I think they are showing another one in
stock here.
Also while browsing ebay, found
this merchant that has a bunch of new 2005-2006 Ford GT parts, including at least one hard to get headlamp assembly.
