First post Front Brake Rotor Sizing

THANK YOU!
This link gave me the part number I needed and was able to order them from metal gear! 
Thanks again for the help, like I May have said in my original post this bike is a bit of a Frankenstein so figuring out parts has been a headache.

This is what I’ve ordered from MetalGear which matches the part number you gave me as well as all dimensions.

ill update again once it arrives.
