81 1000 rear fairing

hope i put this in the right place, lol its late. so i bought an 80 kz1000 rear fairing thinking i could make it work on my 81 1000......wrong. so now i have an 80 1000 rear fairing up for grabs.
i need one that will fit the 81. ive seen a couple different ones online...are there multiples or are they custom made? and is there any way to get one with a light in it to get rid of that nasty rear bumper setup kawasaki put on my beautiful bike?

From your discussion, we can infer you own either a 1981 LTD or CSR 1000. You need to be clear on which bike you are referring to. Dig through this site and look for posts by 'otakar' as he has successfully grafted a period GPz tail onto a KZ1000K frame...this is what you are attempting to do. Contact him to get the details

i have the ltd model, sorry i didnt clarify earlier. thanks for the name drop!
