(Thread made a sticky 7/27/2012)To my knowledge, all SN95 steering racks carry the serial number: F6SC-3550-AA or similar. This serial number basically means nothing as it references the rack housing casting part number and not the mechanicals within. The guy behind the parts counter of your local dealership or joe blow auto parts store probably doesn't see the second serial number which makes a HUGE difference! The second serial number appears as a "dimpled" code on the passenger side near the inner tie rod dust boot. The "dimpled" code denotes the specific valve and torsion bar configuration for that particular rack. This determines the "tightness", weight, ratio, and overall quality of steering feel. The "dimpled" code list below has holes. The whole serial numbering system seems to have holes and I haven't found any definitive information to suggest the process of finding the "right" rack is going to be easy... SPR GY...'94-'96 All (probably not '95 Cobra R, somebody tell me???) SPR RT...'97-'98 All SPR SH...'99-'01 V6 SPR SJ...'99-'01 V8 SPR VT...'00 Cobra R SPR ZL...'02-'04 V6 SPR ZK...'02-'04 V8 SPR ZM...'03-'04 Cobra SPR NJ... the jury is out on this one... From 2003 Manual The 2003-2004 Cobra power steering rack, from what I've read, is just below the 2000 Cobra R rack in steering feel and ratio. It also has limiters, like the R, to prevent the wider factory 275's on 17"x9" wheels (265's on 18"x9.5" wheels for the R) from rubbing the inner fender liner. Now, a lot of this many already knew. But, tracking down a supplier that could actually provide the steering rack you knew about and wanted, e.g. the Terminator rack (SPR ZM), was often based on chance. Since ordering a Terminator-specific steering rack is ideal, the hunt began... Searching for remanufactured Terminator steering racks on the vendor site of your choosing, you may see a company named Cardone. Digging into Cardone specifically, you find that they remanufacture and list their racks based on the SPR XX code. For reference, Cardone's internal code for the Terminator rack (SPR ZM) is 22-2000, The '00 R rack (SPR VT) is 22-280. **HUGE NOTE: I ordered and installed a Cardone remanufactured SPR ZM rack from Rock-Auto. I had to specify the part number 222000 (no dash) when ordering. The rack was drop shipped in somewhat poor condition (Read Post #16) and painted black, covering the dimpled code. However, this rack was installed on a 1997 Cobra and I can say with confidence the steering ratio and weight is dead on with my '04. If you've ever driven a '96-'98 Cobra back-to-back with a Terminator, you immediately feel the difference. I would be hard pressed to distinguish between the two after installing the Cardone unit. Also, it is highly possible that these racks are completely stripped and rebuilt in bulk. This means that even if Cardone correctly installs the internals of the specific model you order, the housing (and associated dimpled code) may be from a different rack altogether. Until I know more, my best advice is to order the 222000 rack, install, and HOPE it's the right one. Another outlet for steering racks is AGR. They have the Cobra R steering rack listed for '94-'04 as part# 715573. http://www.agrperformance.com/Ford-Cars-AGR-Performance-MB-Motorsports.htm If any information here is incorrect, post up or PM me.
