Google'd for ya

"The mounting pad on the 700R4 uses the typical TH350 / manual trans 3.75 inch bolt spacing. The bolts going into the 700R4 are M10x1.5x (length required). Metric torque converter bolts are also required to bolt the converter to the flexplate, GM (PN 1261968)."

I just did this yesterday, I put in a 700R and had everthing working great but had some vibration...Duh! I forgot to put the nut on the mount, because I did not have one that fit, a buddy has a 700R in his shop with an extra side mount on it that we took off a nut and it fit. The nut took a 15MM wrench, not sure of thread size. Good Luck

Sorry, I had to work late, another f@%@&g snow storm. Chevy4life had it right. Here are the metric # including the length M10+1.50+25 or if you think you need a longer one use M10+1.50+30.
