Demort,
What do you replace the rusty blobs with? OEM spec bolts or something else?
I think if going for OEM bolts they should be on a 2 year change strategy.
Any other hints and tips?

We use stainless steel bolts , nuts .. we buy in bulk , not sure where from but probably the same ones you would source from ECP , Design etc .
Need to remember though .. the original 996 ones ( not stainless ) have lasted 10 years ish on average .. some more , some less .. but as an average .. 997 and id probably drop that to 8 .. G2 6 .. best i stop there
The way garages change them is going to be very different from at home and on stands ..
We have ramps , finger sanders , special air hammers and most importantly .. Oxy acetylene bottles .
First off .. with Any stainless nut/bolt you Have to use ally grease on the threads .. if not once done up they will never come undone again .
Been there done that ..
At work .. i can use a finger sander to remove the original flat side of the head ( model dependant ) .. heat it up ( cherry red ) , the flange .. NOT the bolt and either hamer / punch it out or use an air hammer with a long reach end to punch them out , an excellent tool .. dot punch the bolt , then heat then attack it .. literally 6 seconds and it's on the floor !
Or depending on model i'll heat up what's left of the nut ( cherry red ) then chisel it off .. then heat up the flange and knock it out .
Rule of thumb .. all 6 flange bolts replaced is approx 2 hrs labour charge plus parts ..
There are some jobs i tend to say .. just pay a garage to do and this is one of them .. it's just a huge struggle at home , on stands and without the equipment we have .. i for one wouldn't contemplate it should i be in your shoes .
I'm all for helping out here and trying to give advise the best i can .. this is one job that there is no easy answer to .
I'll also add .. its possible to kill a lambda sensor due to the shock of hitting the exhaust too much .. that's a cost that also needs to be factored in .. garage or at home .
Finger sander to give you an idea ..
