1970 Duster Front Brake Conversion Kit for SBP

Hello,

I am looking to convert the front brakes on my 70 duster to disc. Car has 10" drum brakes and small bolt pattern. I would like to keep my existing spindle, axle, etc if possible. Wilwood indicated they do not make a kit like this for sbp but do for the large bolt patter. Does anyone know if other companies make a product that would work?

Thank you.
