    Lots of good reading on the swap in these threads:

    Info on the outer tie rods when using SN95 spindles:

    http://www.foxtbirdcougarforums.com/...read.php?37200

    With regards to the ball joints that is covered in some of the threads above but just use the SN95 style ones in your Fox control arms. Avoids the spacer between the bottom of the SN95 spindle the and Fox ball joint. One other thing that I will point out is that Maximum Motorsports recommends that a person use 94-95 spindles on a Fox car with a stock K-member for geometry reasons. The 96+ spindles are to be used with aftermarket tubular K-members as most aftermarket ones were designed for the 96+ spindles due to the better geometry. With that said...I ran the 96+ spindles on my Coupe with a stock K-member and a taper style bump steer kit and did not notice any issues but it was 100% street driven at that point.

    Meh, I've learned to manipulate the search engine on here over time. Keep at it and you will learn the ways of the dark side as well.

    i have seen several mentions of the Taurus outer tie rod ends being used, but i have not actually seen what year of taurus to get them off of. or for, mind you, as i'll be ordering new.

    i think my plan will be to run 98 inner tie rod ends on my stock rack, and then run taurus outer tie rod ends. I know some have complained about bumpsteer, but i worry how well the bumpseer kits will work daily driving the car on worn out Iowa two lanes.

    I believe it is 1993 Taurus tie rod ends that you want to use in conjunction with the SN95 inner tie rods. Here is how it breaks down:

    Inner Tie Length
    Fox Mustang, Bird, Cougar - 11.50"
    SN95 Mustang - 13.327"

    Outer Tie Rod Length
    Fox Mustang, Bird, Cougar - 5.85"
    SN95 Mustang - 5.45"
    1993 Taurus - 4.30"

    Fox inner and outer = 17.35"
    SN95 Inner & Outer = 18.777"
    SN95 Inner & Taurus Outer = 17.627"

    With all of that doing the SN95 Inner and Taurus Outer nets you about 9/32" additional length over the Fox Inner & Outer. This seems to be the additional length needed to get enough thread engagement for the additional distance the tie rod attachment point is moved outward with the SN95 spindles. Another option is to use SN95 Inner & Outer and cut the Outer to length if you are comfortable with doing that. The reason you have to cut the outer is that fully threaded in it is too long on most cars and you need some adjustment for the alignment shop.

    There is another solution which is keep the Fox Inner tie rod and use the Maximum Motorsports tapered style bumpsteer kit which is what I used on my Mustang with SN95 spindles prior to switching to their full suspension up front.

    Me personally I would get the bumpsteer kit as new inner and outer tie rods will cost you about the same and you have the advantage of setting the bumpsteer. You do not need the bumpsteer gauge for a street car as you can eyeball it and get it damn close like I did. Setting them up with the gauge is better but not worth the effort for a street car that will not be on a track if you ask me. Also, bumpsteer is more noticeable on roads with crowns and potholes than smooth surfaces on a street car. So with that I would be way more concerned with bumpsteer on your worn out Iowa two lanes than a new four lane.

    my intentions were to replace the ball joints and all tie rods ends at the time of the swap, as everything had a very slight amount of play in it, so i cant really figure on one tie rod setup being overly cost effective over another. however, the bumpsteer kit is quite nice, and reasonably priced, considering. did the bumpsteer kit show any wear under regular street driving?

    Put over 20,000 miles on the one set and sold it when I converted to the bolt through style so yeah I'd say they held up.
