Advice on this bolt (Zork + 934 WG)

I have tried all conceivable ways of wrenching this bolt tight, short of flattening the Zork to make room.

The tab is attached to the 934 WG pipe and bolts to the turbo flange.

Brian, you have any advice about this,my current method is a ball peen and a center punch to tighten

Anyone have suggestions on tool mods so it can work?

Don't see how you can get a wrench over that being so close to the pipe.
Try taking the stud out and put a bolt in.
If a regular bolt still won't work, then an allen head bolt using a short L shaped allen head wrench.

That nut is a bad one but always doable. It looks like the tube angle on that Zork may be more sever than it's supposed to be.
I have one of those ratchet action open end wrenches that I use for that bolt.
Another option (that I do all the time) is buy a $1 Harbor Freight open end wrench and modify it to fit using a grinder.
A third option is to remove the zork and put a smooth relief (nice word for dent) to make some room. The 321 is very pliable before heat cycling, so if you haven't blown too many flames out of it yet it will still bend easily.
Let me know which method works for you. In the mean time I'll take a look at making a change to give more room in that area so that conventional tools can always be used.

You could change the nut for a K nut one. A smaller spanner is used to tighten giving more room.

Or replace it with a hex head one, then use a swivel hex drive.

It's the kind of nut used by Porsche on the 3.2 intake manifolds, or starter, where there's little side room.

Good luck!

Those barrel nuts are quite long though.
