14 hours at work. 'nuff said.
anyway, i was able to replicate what i had done, previously, on my 82. it's pretty simple, but it does take some time and patience. hopefully, i can explain it well.
i used:
-the strongest clothes hanger i could find
-needle-nose pliers
-flashlight
1. straighten hanger out. i used almost of the length.
2. use pliers to bend one end over into a flattened hook, with a 3/16" or so gap.
3. run hanger between hood and grill, and BEHIND the front section (the large stationary part, perpendicular to vehicle) of latch. the cable sheath should be partly visible and is a nice guide for where to run the hanger.
4. carefully fish behind the stationary part of the latch until the hanger hook catches on the latch lever. this took a few attempts, the first time.
5. pull firmly, but without jerking, towards the driver's side. until the latch releases. (this is where the long length of hanger helps. it keeps the angle shallow enough to avoid binding and mimics the normal operation of the latch cable. it also allows the whole length of the hanger to flex, instead of concentrating force on the hook end, unbending it.)
this worked for me then, and again, tonight. zero damage. i hope it works for you, as well.
