All you need is a factory hydroboost mounting plate for a '73-'86 C/K or a '87-'91 R/V truck, Suburban or Blazer. Then just remove the factory '99 mounting bracket and install the earlier one. As for connecting to the pedal, some fabrication may be needed. I'm not sure as I have not done anything like this. It would likely be a whole lot easier to just get a '73-'86 C/K or '87-'92 R/V hydroboost and bolt it up.
