    If you want to replace fusible link. Can you just add an inline blade fuse ? And what amp fuse would someone suggest ?

    Different fusible links have different ratings. What are you trying to protect? Yes a fuse will provide the same protection.

      I have to replace my original wire attached to the relay and firewall harness. It’s corroded internally. The original types available I’m not willing to pay $40 for and the more affordable ones have too small of a gauge wire attached. So, i’m going to make my own out of similiar gauge wire as original with a blade fuse. I’m trying to find out what a proper amp fuse would be.

      I just plugged in "Chrysler fusiable link " on the internet and several charts came up, gauge,color code etc.
      Also try www.repairconnector.com and type in "Chrysler". They show a 18 gauge factory style fusiable link for $2.49.

        Keep in mind, different amp alternators used a different gauge fusible link wire...

          My original one is a blue / green its a lot thicker than 18 gauge. Probably 10 or 12. The fuse link wire connects to the starter relay into the bulkhead harness. Where does that connection go beyond that, the alternator gauge ?

          IMO...
          Bill and Rose Evans market Mopar wiring harnesses including the fusable link.

          Regarding the use of a replaceable fuse, it needs to be sized properly to be effective. A mega fuse would be suitable. A fusable link provides a slight delay b4 it opens, to allow for momentary overloads, plus Its easy to replace (relatively). If considering a mega fuse, 30 - 40 amp range would be acceptable providing the total electrical amps do not exceed the fuse amps. Perhaps 10% more than total amps needed to properly size the fuse AND the wiring being protected.

            I believe the original blue links are 16 gauge.

              Thanks, Bob. That’s all the fusible link is, an inline fuse right ? Where does this wire connect inside the dash, the alternator gauge ?

              I have used these type of large fuses. I can bolt it to this stud and bolt it to an eyelet terminal on the wire. Been using this one for years as its a 70 amp. Ron

                As stated above you will find most aftermarket wiring kits use a 50 amp replaceable Maxi fuse.
