Need help removing nut that holds shock in place, I've tried heat, a hammer and chisel... Options

I'm trying to remove the nut that hold the shock in place. I need to replace the strut.



I've tried heat, but maybe it wasn't hot enough. How hot do I get it?

I'm using an 18" pipe wrench. It's the same one I put it on with. I changed the shocks about a year ago. It will not budge. It's hard to put leverage on when it's in the vise. I even hit the wrench with a dead blow hammer. It's currently soaking in penetrating oil.

I tried using a drift and hammer to break it loose. Didn't budge.

The next step would be to use a cheater bar on the wrench. However, I'm afraid I won't be able to hold it in the vice securely enough.

Does anyone have any other ideas?

Thanks!

I bought both the tool from JimmyT and the wrench from Bilstein.

Bilstein tool is #E4-MS08/6. It's 47mm between the tabs, about 54.5mm ID (just fit around the shock tube) and 86.5mm OD. It's 4mm thick.

I ended up using a pipe wrench and a friend to get the nut off. It was really tight. I held the strut in the vise to keep it from twisting while he leaned on it with a pipe wrench. I could not get enough torque on the nut by myself, as the strut is awkward to hold and twists, even in a vise. I also bent the Bilstein tool a little. It didn't help that the recesses on the nut were f'd up from me hitting them with a chisel.

The ball joint tool for Jimmy is awesome. I paid $55.36 shipped. I used an air impact and it came right off.
