Good luck on that one! We had the same problem on a 1942 Pontiac Coupe. It took us several days but we were finally able to remove the grille just enough to get up inside with a long rod to release the hood latch.
I remember that post with the tool Keith. The pictures won't open for me either...the original poster must have removed the pictures from his ImageShack library.
When had hood that wouldn't open, I managed to reach through the grille on my 48 with large long screw driver and open end wrench that fit the square shank on screw driver and unscrewed the centering bolt and spring assembly from hood. If you wear watch, remove it. I didn't and destroyed the band when I had trouble getting my arm back out.
I've posted this before. I totally eliminated then cable on my '46 and will do the same on my '48. Where the cable attached to the hood lock I drilled out the hole on the lock to accept a 3/16" piece of threaded rod may 4-5" long. I put jam nuts on each side and now have a handle to open the hood by putting my had through the grill. I put a piece of rubber vacuum hose over the threaded rod to protect my fingers. Someone would have to stand on their head to see the latch. It's been working well for 15 years. For an original look you can leave the cable in place, just not hooked up.

Don't you have to cut an opening on the panel under the the latch where the cable would attach, to allow your threaded rod system to work ????
No cutting was needed at all. Once the threaded rod was attached I simply reattached the latch as you normally would. The little tab on the latch where the cable attached hangs down low enough and the angle of the latch makes it so that the rod clears the panel. The threaded rod is easily accessible through the grill and a simple push to the right and the hood pops up. It's a busy week but I'll try to get some pictures in a day or two.
Just adjusted my hood and remembered about the difficulties of a busted release cable, so while I had the latch assembly off, I drllled a 1/16 inch hole in the latch arm, and attached a thin cable to it, then ran the cable under the panel through a hole drilled in the driver,s side inner fender. I attached a small handle to it, so it can be opened by sticking your arm up in front of the front left wheel.
I made a tool out of a coat hanger rod that you insert between where the hood and and grill meet. You insert the coat hanger to a marked point on the hanger, turn it approximately 45 degrees, then push the rod and voila! Hood pops open. So simple.
Thanks for the great thread. My 14yo son and I just picked up a 47' Stylemaster. Hood was popped when we looked at it but we let it slam and didn't know the release cable was rusted tight. Now can't get the dang thing open. We got a couple old long skinnies in the screwdriver drawer. Looks like we'll be fabbing a new tool! Thanks for the information.
