I need to know if some different brake and suspension pieces will fit and work together. According to my Hollander interchange at work, these pieces are not interchanging, but sometimes it is wrong, or just a simple fix will make it work. I am going to be running sn95 spindles with an sn95 booster and mc. I guess I have to do a little fabbing to get the booster in? I guess the brake lines will bolt up to this booster with no problem Anyway My car is a 93 4cyl. I have a 90 GT donor car. I want to put the steering rack in from the 90, but according to my interchange the 90 v8 is different from the 93 v8? Will the 90 rack work with the 4cyl steering shaft and column, and the 90 v8 P.S. pump? Also my column is a auto, but I will be running a 5spd. I'm just trying to figure everything before I get too far in. I'm sure I will have more questions. thanks.
Interchange experts inside please

One book you MUST have if you own a fox body--- Amazon.com: The Official Ford Mustang 5.0: Technical Reference & Performance Handbook : 1979 Through 1993: Al Kirschenbaum: Books
Best 30$ I've ever spent on a book. It covers every part from 79-93, and what parts are different, how they're different, when they changed, and why they changed. It also has good information about interchanges, and some popular swaps.
According to that book, both 87-90, and 91-93 steering racks have a 15.01:1 ratio, both have 2.22 turns lock to lock, but the only difference I see is the turning circle. 41.20ft for the 87-90 rack, and 40.80ft for the 91-93, hardly any difference.
Also it shows that the 93 rack has an added umbrella (ella ella ella!) seal on the steering rack's input shaft dust shield.
The only thing it says about the steering joint is that "Two steering shaft couplers were used in production Fox Mustang. The standard coupler has stamped steel U-joints, but the forged steel heavy duty (D9BZ-3A525-A) coupler is much more desirable."
Hope that helped you, my fingers are tired of typing now!

I thought I read that the ratio was 20:1 vs 15:1 on the 4 cyl vs the 5.0. I only mention this because I just bought a 4cyl car and have been reading/searching for info to upgrade my steering and brakes..etc. Looks like everything is stock except the 351W and the 8.8 rear. The brake booster looks to be really small on the car and the brakes are BAD. Even worse than the 87 GT I owned 13yrs ago. Any suggestions on improving my steering and getting rid of that famous 5.0 whine? Also, can I order up some calipers and rotors (front disc) from a 93 cobra for a "initial" upgrade using the current small booster that I have?
Thank you in advance for replies.

In order to upgrade the brakes any, you are going to have to go to a V8 set of spindles, calipers, rotors, and booster, master cylinder.
Or go 5 lug and SN-95 brakes.
