You do not need to make any changes to the inner or outer primary, starter etc, a splined mainshaft will fit fine with no mods there.
Several ways to go here :
Replace you mainshaft with another tapered mainshaft, cheapest way to go because you don`t need to replace the clutch, but that old clutch is a crappy design...
I can send you a used tapered manishaft if you decide to go that way...
I wouldn`t consider replacing just the mainshaft in your current gearset, you would need to use a 1990 mainshaft, it is a one year only design, and the only one that will work with the `89 and earlier gearset.
Find an entire gearset from `91 or later, the later the better.
If you use a `90-`93 clutch it will be plug and play, it will have the same size primary chain sprockets and the same size starter ring gear.

Damn man, I've broken or fixed a lot of hashed harley parts over the years including splitting a case on a 4 speed trans but that's the first time I've seen a mainshaft let go like that, Wow. Your guardian angel was working a bit of overtime or your karma bank is in good standing.
Think Andrews makes that mainshaft still or you can try a dealer but don't hold your breath there.

You've had this conversation in another thread and the answer hasn't changed. To put a reverse on your trike you are looking at a mainshaft , complete clutch pack as the two are very different, inner primary and starter swap to accommodate the different clutch pack . This is hard facts isn't going change no matter how many times you ask it, someone tells you different they don't know the differences in the parts required
