I believe you can research doing anything but once you are into the project you will find many little things that you missed. I am using 96 spindles and gt brakes and all was fine, 96 ball joint will press right into the 89 lower control arm, all 96 brake components work just fine EXCEPT right brake hose has 3/8 thread instead of 7/16 like the left and both of the fox brake hoses. I thought i was going to be forced to buy late model resto's $80 hoses for the swap but my local oreilly auto parts gave me a $2 master cylinder adapter that worked perfect and bolted right in. Just thought i would share this for any one else doing the swap and finding the same problem
