Conversion kit number 91032301 is for the 64-66 Mustangs and should work with the 260, 289, and also 200 six cylinder without problems. You can check with Unisteer/Maval at 800-338-9080 and reference their part number 8001110-01 in reference to any 5 cylinder applications as requested. The 5.0 small block V8 common to transplants will work fine.

How about header fit? And "zero bumpsteer" - can it be adjusted? I have Hooker Super Comp headers and manual trans. I have read that R&P kits have header interference. Product description says there is no bumpsteer,. I made significant CENTERLINK mods (moved the tie rod pivot points) to get to < .02" in 4" of suspension travel. I don't think you can get "zero bumpsteer" with the anti-dive geometry of the upper A-arm.

On the Mustang rack and pinion conversion header clearance can easily be an issue. Take a look at the instructions for this kit here: http://static.speedwaymotors.com/pdf/910-32301.pdf On the page showing the intermediate steering shaft it gives a good idea of the header clearance possible clearance issues to compare to your application. For the bump steer issues zero I agree is almost impossible and lots of things lead to bump steer. On the rack and pinion some of the pivot points such as on the center link and tie rods are gone and the rack basically eliminates them which greatly helps on bump steer. The changes created during suspension travel such as camber and toe in changes are still there but improved using a rack and pinion. Now, for the rack to completely eliminate bump steer the pivot point for the tie rods on the rack end need to be inline with the line of the pivot points on the control arms. Also the tie rods need to be parallel to the lower control arms and the lower control arms need to be parallel to the ground at ride height and weight in the car. With proper alignment, minimum camber and toe in and on a perfect highway bump steer should not be noticeable. But, during the turning radius of any degree alignment specs change due to steering geometry and lean of the vehicle to where the lower control arms and tie rods are not level between both sides which strains the suspension creating sensitivity to bump steer. Unisteer offers great products and we have received favorable comments from our customers on the rack and pinion conversions.

The Flaming River input shaft offered by Speedway under part number 91032318 is NOT a direct hook up to the rack and pinion conversion. The Ididit Column number 4466466 or in chrome is a column replacement to the 64-66 years and has a ¾ x 36 output shaft. So if replacing the column you will need to also get the correct U-joint for the column. The kit comes with the original columns new shaft and the necessary other joints and hardware. Rack ratios are considered differently in racks than in boxes. In relation to a steering gear the rack would have a 20:1 ratio but in reality for technical consideration are considered 3 to 1. Lock to lock varies between the racks and normally in the range of 3 ½ turns lock to lock and in the case of the early Mustangs is actually nearly 4 to 1.

I installed the manual rack unit on my 66 Mustang. It works pretty much as advertised but the steering doesn't return to center like it did with the original steering box. Nothing else was changed. Any suggestions? Thank you, Jack Johnson

With the rack and pinion the car should still return to center after going around a corner if everything is free with no binding in the components. Going back to straight is governed by the caster set into the front end alignment and you may want to check the toe in because if that is off it could influence the return as well. If the alignment is correct you may want to check with tech support at Unisteer.
