Hydroboost Spacer Needed?
1983 Wagoneer 360
Ok im sorry if this is a repeat from somewhere deep in the library of knowledge but I cant find it and i promise ive tried....
I have a 1994 HB unit from an Astro. I have measured the rod length on the VacBooster and the HB unit and both rods are of the same length. Why then is an additional 1" spacer needed? If the rod length was longer then I would understand the spacer but mine appears to be the same from the back of the unit plate to the tip of the rod.
Am i looking at this wrong? Thanks for any help!
