""I only have 10 A66 broadcast sheets on file so far, all 10 show the 74 radiator.

Not all of them show the J54 hood.

Hopefully more A66 owners or folks with broadcast sheets for them either register or contact me.""

Barry,
I do not have a build sheet but I do have a fender tag of my March built A66/J54 car. Would this tag info help any?
