Product Description

Borgeson Power Steering Conversion Kit for all 1965-1966 Mustangs with a 289 Engine.

Upgrade your Mustang's manual steering to power steering with this quality power steering conversion kit from Borgeson! Borgeson's steering box integrates the power assist into the assembly, allowing you to eliminate the power steering control valve and slave cylinder. The stock power steering system is notorious for leaks and providing a vague and over-boosted steering feel.

This kit features a sporty 14:1 ratio re-manufactured modern integral power steering gear box that provides benefits over a traditional rack & pinion conversion, while still offering a similar steering feel and an original look. Each box is carefully assembled, adjusted and inspected to standards that surpass OEM. Does not increase the turning radius like most rack & pinion kits.

Installs easily with simple hand tools and without removing the engine. Includes all necessary components for the conversion. Features a 3 year manufacturer's warranty on the steering box.

-Saginaw power steering pump with mounting brackets
-Power steering box
-Power steering hoses
-Steering coupler
-Replacement steering column shaft with floor mount

*Will require a 2-groove crank pulley (not included).
*Will also fit 1967 Mustangs with a 1" sector shaft.
*Will NOT work with factory z-bar clutch linkage. Must use Borgeson's z-bar if you are using the factory clutch linkage.
*If you want to add headers to your 289/302 with Borgeson Power Steering our shop recommends using Tri-Y headers. Larger diameter headers may have clearance issues.

Borgeson Power Steering Conversion Kit 289 1965-1966 is rated 4.0 out of 5 by 6.
Rated 5 out of 5 by from Great Upgrade I purchased this product to upgrade from manual steering. All the required parts are there as well as an instruction booklet to guide you through the process. Beside the improve my steering I did notice a little bit better turn ratio getting in and out of the garage

Rated 3 out of 5 by from dissapointing pump bracket Absolutely no effort went into designing the pump mounting bracket. Sticks the pump way out in no mans land with no real bracing. Looks terrible! 0 stars for aesthetics. I threw mine in the scrap bin and bought a cvf racing bracket. steering box and the rest of the kit mounted up as expected and work well. If I were to do this again I would buy the box and column shaft separately and source my own bracket and pump. It would cost about the same.

Rated 3 out of 5 by from A good product, marginal hoses, terrible instructi I wish I had installed the hoses before installing the box. They need to be about an inch longer. And we should be warned to not install the pressure hose backwards. The box end is bubble flare metric, the pump end double flare English.

Rated 4 out of 5 by from very nice product very nice and easy to install system. Our 65 Mustang Convertible turns so easy now. My wife loves driving it even more now! would be nice to have a video of the removal of the old and installation of the new...using a Mustang which has a motor with headers on it.

Rated 4 out of 5 by from pump was defective Purchased the power steering pump conversion kit. Unfortunately after a few days, the pump started leaking. No fault of CJ's, pump was defected. Cj's is making it right by sending replacement pump to complete the conversion.

Rated 5 out of 5 by from Not a difficult job to do I watched the video and it seem like it was going to be a bug job. It was actually very easy. I did things a little different than the video.

Product Questions

What's the difference between the power steering conversation kit for the mustang 1965-1966 for a 200-250 engine and the mustang 1965-66 for a 289 engine? I'm changing motors eventually and wanted to see if I can use this kit for the 200 and 289 engine.

Asked by: lilyadi10
The major difference is the power steering pump bracket. The 6 cylinder hoses are a bit longer as well but will still work fine for the 289. You will need a new pump bracket #802409 when you swap your engine.

Will this kit work on my 1966 Mustang 289 stock headers, stock manual steering with a new Vintage Air system on it . The compressor is mounted on the Driver's side up top. Already has 2 groove crank pulley. I don't want to do a lot of modifying.

Asked by: Oldman1949
Yes it should work.

I'm converting a '63 Falcon Futura to a '68 SBF engine. The car came with a Dagenham 4-sp, now gets a Tremic. Which Borgeson unit should I use? I'm also considering a tilt steering column. Help!

Asked by: Steve63Falcon
For a Ford Falcon application you would use either #800110 1" sector box or #800111 1-1/8" sector box. You will need to measure the diameter of your existing to insure you get the correct box. Be sure to measure at the top of the spline near the casting as the shaft is tapered. Additionally you will need to use a cable or hydraulic clutch as the factory equalizer bar will not clear the hose connections. We have not fit an aftermarket column in this application so I would not know what length for you to purchase. You may be better off installing the box and then measuring for column length.

Additionally you will need a 2-row crank pulley to complete the installation. This is not included in the kit.

Hello, I have a 1966 convertible mustang that has standard steering front disc brakes 289 with headman headers. Looking for a power steering kit with everything I need for power steering. Regards, Kevin 

Asked by: Anonymous
The kit contains everything except the proper 2-row crank pulley and power steering belt. If your car has a manual transmission you will also need our #990051 replacement Z-bar.

With this work well with your Manual Quick Steering GT350 Kit (Part #: S1MS3350K) that I already have installed? 

Asked by: My65Ride
The quick steer pitman arm will fit our conversion box. The final ratio may be a little too quick for comfortable highway driving however.

I am utilizing a serpentine belt drive. Are any surpentine pullys avalible for the power steering pump?

Asked by: Rob Tampa Florida
There are serpentine pulleys available. March performance manufactures both a 5 groove #617 and a 6 groove #624 both of these will fit the .750 diameter shaft of our pump. You will need a pulley installation/removal tool to remove and press-on the new pulley.

Just to be sure, will this kit work on a 64.5, 289, stock exhaust manifolds, manual steering? Thanks.

Asked by: Bassman209
Provided your car has an automatic transmission this kit will fit. If you have a manual transmission you will need to purchase our replacement Z-bar # 990051
