Is there a specialized tool designed to hold the crank pulley while you break the torque on the bolt? I tried breaking the torque on my 90. Had it in gear (with the slack taken up) and the parking brake clamped good. The car still moved when I tried to crack the bolt loose. I'd rather not pay a shop to do this to my 89. I watched them use a chain to hold the crank pulley but I can't find a name for it or where to buy them. Anyone have ideas?
