Lovely picture to wake up to on thanksgiving. The fuse blocks are held in by rivets at the prongs they corrode , come loose and even break from heat, moisture and 50 years of use. Clean tem up, and wiggle each prong, if one is loose or cracked, you hit a home run. All blocks are then screwed in against the fire wall. Some times they are loose and one block hits the other prongs and shorts out. Did you move ducting or get to the back of the radio?
Good luck
ENJOY
