I used a Tacoma rack on mine, the ends fit the Mazda spindles, plus the shaft on the rack mounts to the Mazda one easy.
the Tacoma rack will also work with most power steering pumps. I have mine hooked up to a GM power steering pump on my V-8
waz up man.I did rhd on my mazda and i had the steering box shipped over here from new Zealand. It cost about $400 I did that because I wanted it to look factory.Im in the process of making a new firewall, and u will just need 2 or 3 steering universals coming off ur column to the steering box. Good Luck Steve calistyle
