These are front steer units for rack and pinion. I used the stock ht. to replace the 2" lowered spindles that were too low. Perfect fitment.

Speedway’s Mustang II spindles carry the same dimensions as the stock spindles and accept the standard bolt on components. Our upper and lower ball joints match our aftermarket spindles and the OEM spindles as far as diameter and taper of ball joint holes which is 7 degree.

Wilwood 830-10832 WWE Pro Spindle, 74-80 Pinto/Must II, Stock Height
(Part #83583010832)
                        Wilwood's ProSpindle is specifically designed for use in fabricated A-arm suspensions on kit cars, street rods, drag cars and other custom or race applications configured around Pinto/Mustang ll suspension geometry. A redesigned one-piece forged steel body uses common Pinto and Mustang ll tie rod ends, ball joints, wheel bearings and seals. It is lightweight yet nearly three times stronger than OE or aftermarket two-piece cast iron and steel replacement spindles.

Bolt-on steering arms are strong and can be reversed to accommodate rear steer configurations. They also allow the same spindle to be used on either side of a vehicle. Bolt-on caliper brackets attach to substantially reinforced mounting bosses on the spindle body for secure, deflection-free mounting of four or six piston calipers.

Complete brake kits and components including forged billet hubs, bearings, seals, locknuts, calipers, brake pads, caliper brackets, and hats or rotor plates to attach optional rotor styles from 11" to 14" are all available to configure custom brake packages and complete the installation.
