Greg/Gary - thanks for the info guys. I've ordered a repro tool board from Ron, along with a set of wrenches to fit the board. In talking with Ron, he said the wrenches to fit the original board are impossible to find, and any repro wrenches currently available are slightly different so don't fit the original boards. If you have the original tools, then an exact copy seems liek the way to go. If, like me, you're missing the tools also, then Ron looks like the best bet. Thanks for the replies everyone.
As a follow-up note, does anyone have a picture of an original AC Ace tool kit/pouch? I've never seen one, and Ron says that many of them were liberated before the cars ever made it to the dealers, thus their scarcity. Should have the same tools as the Aceca.
