Pricey, but it may be worth it.

for more modern stuff with the 5x115mm
it's not compatible with early Mopars (Fords), 5x4.5"/114.3mm

they have no listings of what the register, 'hub centric size' is either

or 6x4.5"/114.3mm, I didn't even see listed
(Viper & Dakota or Durango 2wd or 4wd, up until they made the bolt patterns different)
not even the truck Ram 1500s with the 5x139.7mm/5x5.5" (1994-2008)
or 6x139.7mm/6x5.5" (2009 - now)

albeit most truck as far as I know come with spares, underneath

anyway, carry on

Of course they do.
The trucks are easy though...plenty of space. The Challenger could have been either way. There are stereo options that take up trunk space which deletes the spare tire.
The development of run flat tires have allowed manufacturers to leave spares out of some cars but those tires are far from perfect.
