You CAN NOT re-use the crank bolt. Its is a torque to yield and stretches. You have to get a new one, unless you have an ARP bolt which is not a torque to yield type. Most people use the stretched old bolt to get the pulley all the way on, then remove it and put a new one for torquing.

use the install tool (or other various methods that DO NOT involve the use of the stock or any other bolt to aid installation) then use a new bolt. be it GM or aftermarket. the old crank bolt is now a pretty paper weight.
one time use only, DO NOT reuse

I would post in your local room to see if anyone has hawk's tool or similar. Some people also make their own cheap $$ version using threaded rod, bolts & washers. Have to look around to find the rod though.

I just went through this ordeal with the powerbond. I ended up making my own pulley install tool with some 16x2.0 threaded rod, some big washers, a nut, and an acorn nut. I got a question though, when I torqued it down it went to 32lb easy, and went about 100* of the 140* really easy. The last bit it got really, really hard all of a sudden. Is this normal for these? The last time I did it it got to like 45* and became a total pain in the *** and I never even got 140*, with 3 people on the bar we broke the 3' breaker bar before we made it that much. I know my first 3 or 4 threads were pretty bad from trying to pull the pulley on with a long bolt, do you guys think it will hold fine?
