If ALL you are wanting to replace is the metal brace that you posted a photo of.. They are not that bad.
The other photos that people have posted are dealing with an entirely different support.
Depending on IF you want to remove the headlight assemblies or just lower them and get them out of the way..is up to you.
The metal support you are showing is held in by rivets that will need to be drilled out using 3/16" drill bit...BUT ..also you will more than likely need a heat gun due to the adhesive GM used BETWEEN the metal support and the SMC body material....which this adhesive provides even more strength....and should be put back in.
If it were me..I would apply the heat on the metal part so it can heat up the adhesive that is touching it and slowing begin the process of trying tot get the metal to come away form the body.. You might find that you might need to heat it up a good distance ( maybe half way) due to the metal bracket is not going to bend. SO...BE PATIENT.
There should be a major mounting bolt in the front center that should also have a thick rubber bushing. This will need to come out to get this part out. I grind paint stick to a sharp taper like chisel and use them as wedges to carefully apply pressure on the body and part to get it to slowly come apart.
IF you find that removing the headlight housing was not good enough and they need to come out....I would re-install them and then take them a part....or the front fiberglass impact bar will need to be taken off..to hopefully have enough room to allow them to drop out form the bottom and still assembled.

should you leave the old adhesive there once you pull the old brace out so that you have a giude?

DUB mentioned grinding paint sticks into wedges. Sometimes exactly what is needed is readily available without wasting labor... https://m.lowes.com/pd/Nelson-Wood-S...75-in/50051789

Hi there Robbie, Is it badly rusted and no longer strong enough to work , it is the piece in your pic ?,how are the other pieces under there ?
So to get at it you have to remove the headlight units completely , the front bumper cover has to come off (I hope you haven't just painted the car). The "honeycomb " impact cover is still probably in the way now so that will have to come off . The big "battering" ram metal impact bumper might have to come off or maybe just loosened to get at the middle of the front support. There is some angled bracing coming off the frame in the front wheel wells , they go out to each front corner , they have to be dealt with. THEN you have to drill out the original rivets holding it onto the hood surround (fibreglass).Sounds easy enough
where in Australia are you ?

di you leave the old adhesive on as a guide to where the new support bar needs to go on or will it affect alignment when you apply more adhesive for the new bar to stick onto.

The header stopped having rivets to the surround panel in 1973, but on the later cars 1973-1982, there was a line made on the ends of the header surround panel which was to be used as a guide for where the header bar was glued. If you look at this link you'll see what I'm talking about.
