Had a Bestem 929 topbox on my '93 ST1100.
I now have this Hondaline topbox from a 2003 ST1300, with mounting hardware.

The Bestem is great for the price ($80), but I can not fit 2 helmets in it, and the backrest pad is useless. With the Hondaline, same 2 helmets fit fine, and the wife loves the Hondaline backrest.
For the adapter mount, I simply used a scrap piece of 1/8" aluminum, about 8"x7", and drilled holes to line up with 4 ST1100 original holes.
Using ST1300 topbox main mount as a guide, and after seeing how it all would look, moved it to the rear about an inch, and drilled it's 4 holes.
Done.
Attach plate to bike. attach main mount to plate. attach plastic top plate to main mount. ready for box.
Anyone should be able to do this and be done in about an hour.
I am an electronic tech, not a painter, machinist or carpenter, so if I can do it.....
Neither ST1100 bike, nor the ST1300 topbox w/hardware have been modified or drilled on in anyway, so can always go back to whatever.
With empty topbox installed, it did seem to shimmy up and down a slight bit with no passenger, so I added below the aluminum plate a piece of scrap steel, 8"x7"x 1/4". Overkill, and might not help, since I did not yet test ride, and reports are on many of the original ST1300's setup shimmy's like that as well.
I will polish the aluminum plate up a little later.
