Actually I do have a few, apparently metal oxide, but shipping them to
you would cost more and take much longer than if you buy them...
Maybe you can use this one:
It's 10W, but still small enough and not too expensive. You can either
bolt it to the chassis, or on a little aluminium sheet that acts as
heatsink, shaped and bent to fit the space you have. These resistors
have lower inductance than old-style "non-inductive" ones, due to their
smaller size. Of course you destroy that advantage if you have to use
long wires to connect them...
Or you can assemble them from several 2W film resistors of properly
chosen values, combined in parallel. Those are very common and
inexpensive. Or use a bunch of even smaller resistors.
