Need info on fusible link.

[runningiron]

I had to replace my flexplate in my 1977 Chevy 1/2 ton pickup 350/350. Rather than completely take the tranny out I loosened up the tranny bolts and slid it back enough to unbolt the cracked flexpate and replace it. I might have disconnected a wire in the wiring loom and I have no juice going down to the starter. More than likely it is a fusible link closer to the starter. My question is, what size wire is the small lead closest to the block that attaches to the solenoid? I have some fusible link material and wanted to replace it as the original is oil soaked and brittle. It had separated one time prior, was not burned up and just spliced it to keep rolling. I never really noticed fusible links near the starter in all the clunkers that I have driven in the past. Do I need a fusible link? Anyone know what size wire that might be? Thanks for your help.
