The '76 in the shop "Gramps" has, or had one of the Warn PowerPlant (or whatever that winch/compressor combo was called) which blocked the latch. The quick fix was to simply cut off the part that sticks out of the grille.
Reaching around either side of the winch and pulling from behind with one finger did the job pretty easily. The hood in this case did open pretty easily, so one finger was all that was needed. But I could see some Broncos I know being pretty troublesome trying to pull at an awkward angle with just the one finger. Have to be pretty strong to do that on some, but in this case it was pretty easy.
