From weld-in frame stubs to full frame conversions, the Mustang II IFS offers a whole lot for your performance dollar. In one upgrade you give your project disc brakes, rack-and-pinion steering, better suspension geometry, and the ability to modify and update with all manner of aftermarket parts including drop spindles, coilover shocks, and more. Many Mustang II setups begin as budget systems with standard stamped steel control arms, small disc brakes, and manual steering. It is a great starting point and keeps the initial buy in at an enticing level for the average enthusiast, leaving plenty of room to upgrade down the road as budget allows. One extremely popular update is adding a power rack-and-pinion unit in place of the original manual Mustang 2 rack-and-pinion that shipped with the IFS kit. Adding power steering provides better low-speed control, especially with larger tires, and allows a smaller diameter steering wheel to be fitted, often providing much sought-after interior room in the small cabins of street rods. Our 1982-1988 Thunderbird rack-and-pinion conversion power steering rack is the perfect upgrade for when you are ready to enjoy the benefits of power steering or as an upgrade to the parts-store reman power rack provided with your Mustang II kit originally. If you prefer the simplicity and clean looks that a manual rack-and-pinion steering system offers, we have you covered there as well with our brand-new Mustang II manual rack-and-pinion unit. Like our new T-Bird power rack, our manual version is built from all new components and is ready to bolt to your original or aftermarket Mustang II crossmember. Superior Build Quality with Direct Fit Ease Have you tried to source an original or remanufactured ’74-’78 Mustang II power steering rack lately? They are getting harder to find and costs keep going up. However, a rodding trick that has grown in popularity is to upgrade to the Fox chassis Thunderbird rack-and-pinion due to its lower cost and ease of conversion. For most aftermarket Mustang II crossmembers it is a direct bolt-on swap thanks to the slotted mounting hole found on these newer crossmember designs. For those with older Mustang II crossmembers you can still fit the T-Bird rack by simply using offset rack bushings to change the center-to-center mounting bolt location to the wider 16-inch dimension used on the original Mustang II. Our T-Bird power rack and Mustang II manual racks are not remanufactured units. They are built from an all-new casting and fitted with all new internals. That includes the rack gear, pinion shaft, internal seals, inner tie rods, and fluid lines on the power version. New mounting bushings are included on the power rack version only and if your mounting hardware has seen better days we do offer a new . When converting from a manual rack to a power rack, some installations may require to properly space the rack away from the crossmember for clearance. We offer these spacers along with the required for everything to mount up properly. We provide AN -6 hose adapters for the power rack’s inlet and outlet ports due to the Thunderbird rack-and-pinion fittings differing from the original Mustang II rack-and-pinion fittings. This reduces frustration and installation time by allowing to be produced on site if your project is not already using AN power steering lines. The smaller 9/16-18 port is the “in” from your pump, while the larger 5/8-18 port is the return to your pump’s reservoir. The T-Bird-based rack uses a 3/4-36 spline input shaft (the manual version retains the stock 9/16-26), requiring little more than a change at the rack end of your steering shaft in most installations. If you are replacing an older power rack, then there should be no change to your steering shaft configuration. If your original manual rack setup needs a replacement U-joint we have to get your new rack installed with ease. The Perfect Solution for Most Any Mustang II Configuration A readily available steering rack constructed from all new components and at a great value, what is not to love? Installation is a direct replacement for your manual rack in most instances due to the same Mustang 2 rack-and-pinion dimensions, and our T-Bird-based power steering rack will work with most any used in a modern serpentine belt drive or V-belt setup, including the Ford CII, GM Type II, and GM Type I (more commonly known as a Saginaw pump). These pumps output the necessary 1,200 psi required and flow approximately 3 GPM. We offer a multitude of in both V-belt and serpentine for Ford, GM, and Chrysler engine families to add the pump of your choice to your engine. Since there are so many variables that affect a properly functioning power steering system, including vehicle weight, alignment, steering wheel diameter, tire width, steering ratio, and much more, some applications may feel twitchy and may require a reduction in flow. The GM Type 1 and Type II pumps utilize that can easily be swapped out to adjust the flow down to aid in steering twitchiness and prevent steering dart due to an over-boosted power steering system. Another option is an where you can dial in the exact steering effort you wish easily. This means you can have the system turned down for more effort when needed for a track day, but then it is easily turned back up to reduce your steering effort for daily driving. This is your best solution when using the Ford CII pump in a Ford-powered application as well. Installation Tips Use bolt kit to bolt rack directly to the crossmember Use bolt kit with rack spacers if extra crossmember clearance is needed converting from a manual rack Rack mounting bushings included with power rack version, but NOT manual rack version, use bushings for manual rack Offset mount bushings will be required if the crossmember only has 16-inch center to center mounting bracket holes Overall width of steering rack with inner tie rods is 45-1/8-inches Compatible with standard Mustang II outer tie-rod ends, such as Bump steer kit can be used in lieu of outer tie rods if desired If rack extensions are necessary for your installation the power rack requires 25mm-1.25 thread extensions and the manual rack uses 14mm-1.50 thread extensions The power steering rack has 5/8-inch and 9/16-inch O-ring style ports which will not work with inverted flare fitting-equipped power steering lines The power rack is an OEM replacement for 1982-1993 Ford Mustang, 1982-1988 Ford Thunderbird, and 1984-1988 Mercury Cougar but will require aftermarket AN pressure and return line kit to connect to your factory pump The manual rack is an OEM replacement for 1974-1980 Ford Pinto, 1975-1980 Mercury Bobcat, and 1974-1978 Ford Mustang II We suggest the Sweet brand u-joint for DD shaft or for 3/4-inch round shaft for connecting the manual rack version to your steering shaft 15-inch or larger steering wheel recommended when using manual steering rack Intended for front of crossmember mounting applications only, will not work on rear mounted applications Specs Tube O.D. 1.42 MFG.
