Default Catalytic Converter Purchase?

Hey Lads,
I have a persistent P0430 and I am on the hunt for replacement cats.
Have looked at several online sellers with prices north of 1400 a piece so too rich for my blood.
There are some on ebay selling a EPA version for under 400.00 but the listings are odd in that they say "Rear" cat - not a left or a right version. They do look like the proper setup with 4 bolt flange on one end and 2 bolt exhaust flange on the other but I am curious about the way they list them as being rear.
Anyone purchased and installed these on their 2003 or newer XK8?
Here is a photo of one of the ones listed.

Bummer that those are not the proper ones for my model year. Thanks for the offer.

If anyone else has 2003+ cats, I would be interested. I placed a WTB in the marketplace but in case anyone has any that do not view the MP, please shoot me a PM.
Need them to get smog

For my own confirmation, bank 2 is the driver side correct?
On NA cars of course.
My failure is on bank 2 and as much as I would like to find a nice lower mileage set, I can get away with the one that is causing the code.

@razorboy talked with my indie today - he doesn't have any used and say it's a crapshoot with what you get. His recommendation is to check local exhaust shops and find someone that can custom the exhaust to use universal performance cats. They can be moved under the car. He is going to check his sources for new, but thinks Walker still lists them. I looked up Walker and came up with the following - which the first link looks like they may need that custom exhaust; the second says customizable so may be worth giving Walker a call:

https://a-premium.com/brands/walker?...&attributeId=5

https://www.walkerexhaust.com/find-m...ults.html?type[value]=2%2C8&type[label]=CONVERTERS%20-%20ALL%20OTHER%20STATES&year[value]=2003&year[label]=2003&make[value]=20&make[label]=Jaguar&model[value]=102&model[label]=XKR&catalogId[value]=converters-allotherstates&catalogId[label]=CONVERTERS%20-%20ALL%20OTHER%20STATES

Very appreciative for the help on this.
I will do some research.
The idea of building a set starting creeping in this morning so this is good timing.
