DC Power Plugs for HP/COMPAQ NC8430

I have a box full of ac and mobile power bricks for the last couple
families of HP Laptops.

Every significant model roll seems to change the dc power plug specs,
but little else, so I have simply put new plugs or adapters on the
ends and used all my accessories without issue (a volt or two here or
there is likely within the specs of the power bricks...)

My new NC8430 has a power plug that could probably be used for arc
welding leads.

The AC power brick model is (pick one):

PA-1900-18H2
hp p/n 384-021
REPLACE WITH HP SPARE 391173-001

output:
90 watts
19 volts
4.7 amps

Approximate physical specs:

OD - 7.40 mm
length - 12.5 mm
ID - 5.0 mm

I have searched all the local geek hardware shops, Fry's, etc. Ford
Electronics in Fullerton even took pity on my and has gone to all
their suppliers with a result of: nada, zip, nichts.

I am bewildered that I need to spend more than $150 to get a mobile
and additional power brick for this thing when I have a trunk full of
them.

Suggestions?

Cut the AC adapter's DC side in the middle and use connectors you like, to
reconnect it then swap that pigtail beween whatever mobile adapter when
you need to.

Thank you for your reply --> I've been doing that kind of stuff for
over 40 years.

The question is, where to find the damn plug.

No clue where to get the connectors. I'm not sure why everybody but IBM
has to change laptop power cables connectors every 3 minutes, and to
always use weird connectors in the first place.

It's possible they're from a company like hirose or stewart, but good luck
trying to cross reference them or finding any place that will just sell
you a few. You might try digikey.
