There is something so satisfying about these old basses, especially when you can take one and bring it back to life. I’ve posted many pics of my HondoII I got in 1981, which was my first bass. I found it in my parents basement tucked in a corner, didn’t even know it was still there. It was gutted and didn’t have strings on it, but bringing it back to life was fun. It was my first bass, and has a special place with me. The best part, as I’m sure you have found out, is many Fender pieces will retrofit onto the bass. In fact, a USA pickguard will come close to fitting, and the trussrod cutout is perfect. If you wanted to turn it into a traditional P style bass, the pickguard would make a great template. Just thinking out loud.
I put the USA pickguard, replaced the electronics and pickups with DiMarzio model Ps, and replaced the corroded brass bridge with a Schaller I had (it fit the stock 3 screw holes perfectly)and it’s back to business. I would suggest taking the bass in to a seasoned luthier when you get the nut replaced, as a standard Fender but blank won’t work. They will have to form one out of stock.
Anyway, good luck and hope to see pics once it’s all done. I do love that sunburst! Very old school Japan looking! I’ll post a shot of my baby so you can see the mods.
