Could some post what I should be seeing if correct. Zoom in on last pic and you can see outboard bracket. Trying to also determine where that attaches.
Thanks…..

Yes, I believe the tab on the one side is to clamp the cables in place, not mount to the case.

On a different note, I see you installed turbo valve covers on the exhausts. If you ever plan to check/adjust the valves with the engine in the car (and bolted up) you need to mill/shave some of the fins around a couple bolts. Otherwise they won't clear the trailing arm frame mounts. There are a couple threads about it.
Ask me how I know..

Yes kind of……..not sure I know what you mean on Z bracket….i see a bracket on outboard side and assume it must attach to something.

On valve covers ……will be changed before installing in the car…..but have a set of original look alikes ( SC) that are aluminum and purportedly won’t leak. (IMG:style_emoticons/default/dry.gif) vs magnesium originals. Now to find them.

The mag ones on my motor were very warped ....some clown had installed 2 thick gaskets to stop the leaks then wound them up real tight (IMG:style_emoticons/default/slap.gif) .
Glued some sandpaper on to a sheet of thick glass and resurfaced then which took a lot, refitted them with beaded VR gaskets and they only lasted around 300 miles and started weeping, shortly after they started dripping .
Purchased a set 930 covers , checked them and both benefitted from a resurface but not a lot on one but the other required a fair bit of work , IMO the worst of the 2 would have leaked otherwise.
Cheers.

The tab on the passenger box has two functions, it keeps the box from rattling
and provides attachment to keep the cables from drooping.
On the drivers side there is a small leg from the box to the forward exhaust stud
to keep the box from rattling, another bracket on the outside top surface is used with
a Norma hose clamp to keep the oil hose from contacting the heater box.
IT can be seen in 'six addicts' bottom three pics.

Sorry to belabor this but trying to determine where or what this one attaches to.
Circled in red.

Hoping this is final question.

Final answer. (IMG:style_emoticons/default/smile.gif)
That bracket is on the drivers HE on the top surface of the heater box.
It keeps the oil cooler hose from resting on the heater box. It works with a 30mm
clamp as pictured.
It's the hose that goes from oil cooler to oil tank.
