So I need a new one, I don't however need a bump stop or a spring seat, however, to replace the bracket would I be as well to buy the other two as well?
YRM do the bits, Glencoyne Engineering will be doing the work but I'm afraid once it is pulled to bits its gonna need all the bits rather than just the radius arm bracket as they are all welded together.

Anyone ever done this repair before?

This is the bit it needs, the radius arm and panhard bracket.

Front Axle Part A Radius Arm & Part B Panhard Bracket (welded together) n/s - YRM Metal Solutions

Would it cost anymore to just get a new axle case from another vehicle? No worries about how the repair is done either.

ive done the repair with the bit you have in that picture.

my advice in hindsight would be - get a new casing.

at the very least get the shock mount as well and do it as a oner - Its a horrible job and by getting the shock mount too you dont limit your access to try and disect it. You just hack it off.

that said it aint glencoynes first rodeo and i will admit when i did the second side it was much quicker than the first.
