...JB1490 is Correct! I have a 74L with the Front Grill mounted with Screws easily accessible from outside. IF one were to have their cable snap, and there is No second, back-up cable, I believe one could remove the grill and Reach-Up with a 10mm?? Open-end wrench (perhaps a 'Ratcheting' Box-End-Wrench) and loosen/unscrew the Hinge Bolts, off the Hood itself. You just need enough Hood movement, forward to slide the Pin out of the Latch...approximately, only 1/2" at Most.
A Note: I do have custom fans mounted to the Radiator, so the Original Fan Motor MOUNTS were completely removed Years Ago. Accessing the Hinge Bolts will depend on Your Situation.
