@Upt' North and
@dwalby , you both have a point here, but
@Phunter103 has the bike he has and he's trying to make it his own within the means available to him. I suspect most of us here are older and have the means to source that elusive part to make our ST whole no matter the cost or challenge in finding it. That's what *I* would do.
But
@Phunter103 will be happy with bar-end mirrors and some universal indicators to get himself back on the road and keep his mount DOT legal.
Unfortunately there's currently little to no market for the part you seek
@Phunter103 .
If I were doing this I'd source the 6mm bolt with a suitable washer to secure the upper fairing to the cowl stay. Though the mirrors spec two bolts per side, I think without the mirrors one per side would do the job. Then rather than using the mirror mount bolts for the cosmetic cover, use the screws that hold the clips which the posts in the mirror cover connect to. I'd probably do it in two phases - first just to cover that area for cosmetics; that could be done with a thin sheet of ABS you might find at a hobby shop and cut with a saw or even scissors.
@paulcb has the right idea that the shape you need is right there on the upper cowl of the fairing. And later you might follow up with a more sculpted, aesthetically pleasing effort that could be 3D printed or even vacu-formed over a buck you might carve out of wood (or even use the 3D printed part for that).
Good luck! We'd love to see what you eventually come up with!
