Baba 30 spreader measurements

I had planned to make a new spreader for by Baba 30 while home in California this winter but when I did the drawings of the spreader I some how did not transfer the thickness at either end. I can't go down and re-measure as the boat is 2000 miles away. Does anyone know the spreader thickness where it mounts into the mast mount as well as at the tip?

Thanks
