could someone outthere please tell me what rear end fluid an 89 sc uses. my hayes and chilton manuals are usless on this subject. i am changing it this weekend so the faster the response the better , thank you
 
I used Redline synthetic 75w-90 gear oil. This already has friction modifier in it, so you don't need to add any (it won't mix right with synthetic oils anyway). If you're using dino oil, you'll need the friction modifier from Ford.
