    Well, to make a long story short, I am replacing my K30 hydroboost system with a vacuum system due to full hydro steering. I want to keep the hydroboost style pedal assembly. The hydrobooster has the 8" long shaft with eye on the end that connects to the pedal. Appears that the vacuum booster for the same years has a threaded end (not an eye). So is there another short linkage with an eye that screws into the booster shaft? Can someone look at their pedal assy where the booster shaft connects and tell me what you see, or even snap a pic?

    Yep, there's a threaded rod with an eye on it.

    The hydroboost pedal has the mount for that eye in a different place than the vacuum; it's maybe an inch higher, IIRC.

    If I were you, I'd go junkyard hopping to get a pedal and the rod end, etc, as trying to fab anything or fudge it by hand is gonna suck.

    I recently went the other way, vac to hydroboost.

    I can send you pix, but that's the basic difference.
