I just remembered that I had these in my computer already...no measurements but I'll try to get them for you in the next day or so...you can at least see where it sits in relation to the other fixed points on the hood. This came from a '67 coupe (it has the unique '67 only latch and receiver). I held a '69 style tach up to it (repro) and the spacing for the mounting holes is much larger (as one would expect).
