Picked up an M8540HDNBC10 and it has the wider wheels on it. We need to get this squeezed down to the factory claimed 48" width for our planned use.

Parts lists the narrow front wheels and they are available. 16x8

Parts also lists several rear wheels. 8 bolt pattern, W10x24 and W12x24 and maybe something else but does not list the width on the third one.

The narrower rear wheels are not available and they do not list a replacement. It's listed on the parts as available, but the dealers I've checked with say it is not. I'm checking with new sales now, but no luck so far.

Not found any narrow tractors at the salvage yards and I would consider these to be rare beasts in general.

Any suggestions on where I might source these? Are there aftermarket wheels that would fit? Are there ways to change the offset on the 12" rims to make it narrower?
Is there a source online that you can pick through "new sales" items such as this?

The rear wheel assembly we are after:

The wheels and centers commonly used with Ag (R1) Tires can often be adjusted for width. Some R4 (industrial) and R3 (turf) are not adjustable for width, depending on the tractor.

This is not your tractor model, but it shows adjustment options for an "L" series Kubota:

AGWHEEL EXPRESS is a good source for rims since you should be able to reuse the disk. If you need tires I would just order the whole-goods assembly from the dealer.
