Tail cowl interchangeability

[Unap]

Hi to all you precious brick members,

I just accuired a sweet early -85 k100Rs. It's mandarin yellow with a red frame, absolutely gorgeous *cough cough*. It's also crashed, a bit. But it runs sweet and has only 32k km on the odometer (original instruments). Now I also got it registered, and what an enjoyment it is to drive! Sure it lacks half the fairings and has no oil in shocks (it's like driving a rocking chair), but it brings a slightly scared smile on the face :)
My plan is to build it to something. Cafe would be nice, but I already have an awesome Ducati cafe in the garage. So, it will become a cafe-ish tracker.. something that looks cool, but a bike that you would feel confident to take around the world.
But before that I would like to get it in moderately into shape, so that I get the right brick feeling. For that I need the rear cowl (upper and lower) among other things. And my question is, are rear cowls interchangeable between different k -models, and if not, how dramatically (something you can get past with a hammer and grinder :)?

I'm sorry. I prefer best original than café.

Well, Ok.
Thank you for your input.

Tail cowls should be interchangeable between years but you'll also have to change the seat and hinges at the same time, because there was a re-design in 1986.  Low seat option also required new seat and hardware to replace the standard seat, hinges and tool tray.

84-85 K100's had the passenger grab bar in the seat. later K's on the rear cowl.  Seat, rear cowl and battery covers, tank, footpeg mounts, gas tank and other bits are unique to the early model.  The engine also had slightly hotter cams, giving a couple extra hp.  Not sure if the cowl-seat-sidepanels interchange easily.
