Since these are 43 mm forks, you will have to swap out the entire front end and not simply slip the tubes up into the stock triple trees (bonnie forks are 41mm). Given that, you can use any year you wish since you need to adapt the triple trees/install the correct fork stem to get this to work.

Rear wheel fitment is unknown.

Another possibility is VTR1000 (Superhawk) forks which also have 41mm tubes. They
have the advantage of 4 piston brakes which the F3 didn't have. The rear wheel on the
VTR is wider than the rear on the F3, so F3 wheels would work better on a Triumph.
I don't know if the F3 wheel would work on VTR forks, but I suspect that it might.
Disc diameter is the same (296mm) and fork tube spacing is the same. Just a thought...

If you want to run the stock wheels you need to build a franken-fork with the cartridge and tubes from the honda fork and the lower legs from the Tri. Its an excellent opportunity to get springs matched to your weight and if you think its worth it you can install gold valves.
