Thanks everyone for the advice and especially the humor!
Sorry for any confusion - I do not have the seatpost yet. It should arrive next week. I was hoping to get the dimensions ahead of time, before my seatpost arrives.
I thought I might get a pair of replacement hex screws ahead of time. But it sounds easy enough to keep the stock bolts. And the original Campagnolo bolts have a nice fit in the yokes.
I do have tools for measuring thread pitch, along with a variety of 10mm wrenches, sockets, nut drivers, etc. I like messing around with them, but I rarely find them in the road.
