You're going to need to use a meter to pin out the wires, or at the very least a test light- and check the positive wiring to the fuse block, until you find the section that has the fusible link in it. The wiring usually feels a little softer (the rubber coating) and may be imprinted, though after this much time it may have faded- or it may even show signs of heating where the link blew.

I have found them. My question it do I cut and splice in new ones They are located by the starter solenoid I believe And covered with soft rubber. Can I splice in regular fuse. And what size should I use
Expert:  gomi_otaku replied 5 days ago.

The fusible links CAN be replaced with a fuse, but you need a certain kind- a fusible link is designed to absorb the "pulse" of a starter current without blowing like a fuse might, but also when it DOES blow, it blows completely- a fuse may have a small enough gap that if there is a major current through there, it can jump the arc gap.

The fusible links are rated based on the color of their plastic sheathing, which shows the wire gauge.

HERE is a good page to take a look at, with information about what sizes and types of fuses you could use to replace the links
