Product update: The rebuilt power rack # 910-34340-POW as described here and in our previous catalogs has been phased out and replaced with a new rack # 910-35341

Fits aftermarket Mustang II crossmembers. Available in manual or power steering. Mount bushings are included with the Power version, but mount bushings are NOT included in the Manual version.

MANUAL: New manual rack and pinion steering assembly for Pinto/Bobcat/Mustang II based front suspensions in street rods and kit cars. 9/16"-26 spline input shaft. 16" mount centers. We suggest the Sweet brand u-joint 910-3247 or 910-3227.  The Unisteer U-joint tends to run big on this joint.

POWER: New power rack modeled from the 1982-88 T-bird design which will work with aftermarket Mustang II crossmembers. Bushings included. (Can be used with a Saginaw GM power steering pump without any additional valves or inline pressure regulators). Overall width is 45-1/8" with 15-1/2" mount centers. Must use offset bushings (910-34342) to mount to original Mustang II crossmembers. 3/4"-36 spline input shaft.   Uses 910-4047 -6AN adapter fittings.   Rack has 9/16"-18 female o-ring pressure outlet and 5/8"-18 female o-ring return line threaded ports.  Replacement sku for rack and pinion hard lines is 910-35344.



  1. The Power Steering unit has 5/8" and 9/16" O-ring style ports. If you have an inverted flare fitting on your existing lines, that will not work.
  2. The Power Steering unit can be used with our standard GM pumps 91032922-GM, 91032908-BLK & -CHR, and with hose kits 910-32535 and 617-4835.
  3.  Applicable Bump Steer Kit # 721-BAX102 now available when application may require.
Some parts are not legal for use in California or other states with similar laws/regulations
