Will it clear your wheels?
This is the red-caliper version. Hub offset stays at zero, but wheel diameter alone won't tell you about caliper clearance. Put the template against your actual wheel. The spindle and five-lug pattern still need to match.
Fitment
1974-1978 Ford Mustang II, 1974-1980 Ford Pinto and 1975-1980 Mercury Bobcat with the required original factory disc-brake spindle.
A Mustang II suspension swap in another vehicle is a component-matching job. Aftermarket/drop-spindle suitability needs manufacturer confirmation; no additional vehicle years are inferred.
Specifications
Part 140-10742-DR; red powder-coated six-piston Dynapro 6 calipers and 12.19 x 0.81-inch SRP drilled/slotted iron rotors with black electro-coat.
Published hub offset is 0.00 inch. Aluminum hubs offer 5 x 4.50 and 5 x 4.75 bolt circles with 1/2-20 wheel studs; existing four-lug wheels do not match these hubs.
Included
Two calipers, two drilled/slotted rotors, aluminum hubs, rotor adapters, BP-10 pads, mounting brackets, bearing cones, grease seals, dust caps, studs, shims and listed assembly hardware.
Before ordering and installation
Use DS-644 Figure 2 and verify the wheel rotates freely without interference. Some 15-inch wheels clear; check the actual wheel.
Wheel contact surfaces that overhang the aluminum hub face require separate Wilwood 300-11961 spacers. Stamped steel wheels without overhang should use separate 300-10716 hub shields.
Inspect the original spindle and bracket surfaces, keep the OEM spindle nuts/locks and follow the exact bracket/shimming procedure. Cotter pins are not included.
Flex lines are separate, and OEM lines do not attach to these calipers. Wilwood lists 220-8307 for this kit; verify fitting sizes, routing and clearance for the actual installation.
Match master-cylinder capacity and front/rear brake balance, then bleed, bed and test the completed system by the manual before road use.
