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

[914 RZ-1]

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 have an email in to Bilstein. I'll let you all know what I find out.

I found what appears to be the right part here:
https://www.mk1autohaus.com/Bilstein-Strut-...7mm_p_8039.html

But when I went to my cart, it took me to a page that redirected me to an Ebay store that is no longer active. No credit card info was entered, but I thought it was odd.

I think the dimension refers to the inside distance between the two tabs.

Prices are all over the place and most sites have no info about the dimensions.

I'd prefer to use the right tool, especially since it works with a 1/2" socket. My breaker bar is 24" long and it will provide me with lots of leverage.

However, I might have to just get a hooked spanner and use that with a piece of pipe.
