Vacuum to Hydroboost conversion
I would like to install the hydroboost system from the donor vehicle into my 1990 Suburban. If anyone here has done it, please report if there is anything in particular I need to pay attention to. Also, will the ABS system work with the hydroboost?

Re: Vacuum to Hydroboost conversion
Not sure on the ABS part, but to do the hydroboost swap is pretty straight forward, although you should use the hydroboost pedal as the hole for the rod is in a different location, or if you have a hydro clutch, use the hydroboost pedal for reference and redrill you current pedal.
If you are using a saginaw pump, then just use the donor for the second return line. Also, if I recall right, there are two bolts/studs that will need to be either removed or added, but you'll see what I am talking about when you disassemble the donor and then pull off your vac booster.
