Hi Dean,
You would be better getting touch with the guys at 1-Jac Dean.
I know that after 1-Jac changed hands, the new guys spent months going round the UK with their 3d laser-imaging gear re-doing loads of bikes to make the mounting adaptors a better fit (or getting the template for bikes they had not done before).
One thing I am pretty certain of is that if they do not have a newly imaged 2019 model adaptor kit they they will bend over backwards to make a new 3D image of your bike and get you the right adaptor plate.
They are an excellent outfit to deal with.
Regards
Carl
