I've got the KD tool, but welded a 3/4" nut on it years ago to use a ratchet. Used to do lots of them on smokin' used cars(mostly brand X) back in my tech. days. I always just brought the piston to t.d.c. and never used air or rope or anything.Unless your piston is 4" down the cylinder at t.d.c.(!)where's it gonna go?Haven't lost one down the hole yet.
