I have a chance to get a set of front brakes,spindle and all for my 70 Dart.I have 9 inch brakes on it now.The parts are from a 70 also.Will this work and can I get the bigger bolt pattern discs on the new spindles?
The disks you are looking at are the Kelsey Hayes disk brakes. They are small bolt pattern and parts are not easy to get and are more expensive. You want the disks off a 73+ A-body for the big bolt pattern and parts availability at the corner parts store.
