I don't know for certain but if I had to guess, they're M8, M10 or M12 coarse thread. Been too long since I had my balancer off.
I'll check it out this Saturday. Do you happen to know the proper torque needed to install the new unit? My buddy is saying that it's 180lb torque, but I've read elsewhere that it's less.
 
Umm...you are not using a 3 prong puller ? You are talking about the crankshaft pulley yes? You should not have to us any bolts except the factory one on a three prong and us that

As to torque specs, the crankshaft pulley should be torqued to 66 ft lbs, then loosen 1 full turn, then torque to 37 ft lbs and then tighten 90 degrees (1/4 turn)
