I have the disk brake conversion kit from speedway. This mounts up to Ford round back spindles. Been mounted the car and had wheels and tires on them but were never plumbed in. Brand new with 0 miles. 4x4.5 bolt patter. 200 Obo plus the ride. You can use this link to see what kit it is. http://www.speedwaymotors.com/Disc-...-Early-Ford-Spindle-5-on-4-1-2-Inch,4575.html
