So I swapped out the plungers on the HW rope gripper today. I meant to grab the model# but forgot. It's the big one, two plungers, three springs on a nasty freight. Not as bad as I thought, Took about 3 1/2 hrs. Three items I wish I had but didn't, hammer, drift pin, about a ten inch long 5/32 allen wrench. All in all I'd say it went pretty well.
