I'm parting out a '97 3/4 ton burb and it's got Hydroboost. Probably will just try to sell it, but just curious if it's possible to retrofit to my '91 Burb. Would the booster unit bolt to the firewall and connect to the pedal rod OK? And then for the pump - the '97 serpentine setup is different than '91 so I'm curious if the pump would bolt in there or not. The bottom line question: is it worth it? I don't tow a lot now, but am hoping to get into the travel trailer game soon.
