There's another possible solution, if you don't trust plain cables: make your own.
The spec is quite clear in the Ethernet specification.

I built a bulkhead cable for the DEQNA card using a shielded (but untwisted) joystick
extension cable. Ultimately, I found the actual bulkhead cable, but mine worked just fine.
Granted, it was only 1-foot long, but untwisted probably wouldn't matter for a short
length as Paul mentioned.

Hi,
Does anyone have any AUI cables for 10Base5 that they would be willing to sell?
I'm looking for a couple of them 1-2 meters long. I will eventually* need them for
my 10Base5 / Thicknet / Hosepipe network segment.
In ham radio net style, chat on list, and conduct business directly / off list.
*I still haven't found sufficient Round-to-Its to get off my posterior.
I can see them still for sale as current products.
One is from Black Box, at an insane price, with actual AUI style (slide lock)
connectors.
There are several others that are much less expensive, with regular screw lock DA-15
connectors. And of course cables with those connectors are readily available from the
usual suspects (I like L-com).
The question is whether "plain" cables are electrically adequate. Most
likely yes, especially in the short lengths. They might not be twisted pairs and/or
shielded per spec, but if you're only going a meter or two, that's unlikely to
matter at 10 Mb/s rates.
FWIW, there exist adapters from slide latch to screw lock DA-15; I have one I bought
from L-com so I could attach a 10BaseT transceiver with slide lock posts to my Pro-380,
which has a screw lock DA-15 connector for its Ethernet port.
