This seems worth bumping as I cannot find any new fusible links in stock.. well I found a few examples in stock on eBay for $250..
The way I am reading this chart I would need two 15 or 20 amp fuses for the body harness to closely mimic the original configuration?
Seems like something like the SafetyHub 150 would be a nice box to run everything though with some room to expand later. Would also make a nice way to do a direct run from the body to alternator.

so like Georgle_tlc said above, derating for temp is important. Here is the midifuse chart and
Datasheet
Here is the fusible link diagram from the FJ62
Per Coolerman
".5mm fusible link = 20ga fusible link
.85 mm fusible link = 18ga fusible link
1.0mm fusible link = 16ga fusible link
1.25mm fusible link = 16ga fusible link
2.0mm fusible link = 14 ga fusible link"
So assuming the "4 number" difference:
0.85R Yellow is protecting a ~14ga wire
0.5G Red is protecting a ~16ga wire
1.25B White is protecting a ~ 12ga wire
0.5G Black is protecting a ~16ga wire
0.5G Black/Green is protecting a ~16ga wire
If nominal and max currents on each one of those could be measured, a suitable fuse could be selected. Their are standard ratings for each gauge of wire, but it dependent on length
