Looks like you need a new battery connector clip as well. That one looks rusted beyond recovery.

Being of a certain age and seeing them in shop windows, I know Hondo weren't known for being expensive guitars, even their top-lone models, so having DiMarzios and Grovers (both all-US made brands) at that time seems unlikely to me, especially for a Japanese made guitar. Gotoh, being Japanese, sounds more realistic. Some of their better models may have had DiMarzios, but that doesn't mean that all the models had them.

Standard DM Super Distortions certainly had an ID stamp on the back plate. On the other hand, these have the distinctive hole pattern on the top of the bobbins that the early Super Distortions had. But then SDs had a braided single wire connection lead, so they aren't SDs. They may possibly be Dual Sounds, which were 3-wire versions of the SD (the two coils were linked at the pickup end, with a tap wire running out for single coil operation, rather than taking leads from both coils out as happens in a 4-wire pickup) but they always had black leads. Also, I've just noticed the extra blue lead coming out in addition to the grey lead, which seems very strange to modern eyes. So I'm erring towards these being Japanese Dual Sound style copies.
