Please clarify, the lever under the dash or the latch under the hood is
Either way, the only option you might have is a salvage yard to get a
new cable, inside lever, or hood latch.
You might be better off taking it to a dealer, but even they might not
be able to order these parts, if that model car/year is "obsolete"
(meaning you can't get model specific parts for it anymore).
The first step would be to give a Ford dealer parts counter a call and
ask for prices on those parts, if they cannot be obtained they will
tell you "obsolete".
If you're handy with tools, the salvage yard is always a good option
for situations like this.
