SSBC A-153 Front Drum to Disc Brake Conversion - Non Power - 71 Demon 340

Don't they require offset shims between the hub and rotor?
I dont know.
Have you connected with SSBC? I have been using their products for 20 years and always found them responsive. Why look for rotors elsewhere when they should make this right?

Confirming the Kelsey Hayes set up uses a different spindle than drum brakes - that's the point of the SSBC set up, adding disk brakes while using the drum spindle and suspension components.
Oh I have been in contact with them on many issues... wrong brackets, brake hoses too short. They had to machine a new castle nut because the one in the kit was wrong... had to send them videos to prove the studs were off center. Yeah this has been going on for months. Now I wait... again. I m not one to bad mouth a Company I deal with, but the facts of this process will end up on every Mopar group, page, blog etc. and the readers can choose to buy SSBC or not. Im all about buying American and small businesses, all I want is for you to stand behind your product, nothing more.
