i just did this to my 89. it had the complete bendix ABS junk. and it was totally locked up, meaning it barely had any brakes no matter how hard you pushed the pedal. i removed all the ABS equiptment, and removed the pedal assembly. then replaced the pedal assembly with a 95 and used the same 95 brake booster and master. it was a pretty easy swap. i got all the 95 stuff from a junk yard donor. i kept the short brake lines attached to the master and proportioning valve, which i also took from the 95. i ended up messing up the sealing area on the 95 prop. valve, so i reused the 89 prop valve which was identicle except for the mounting plate. the stock valve just hung there via the brake lines. it all worked great and had no fabrication needed.
