I'm curious about going this route as well. I'm converting from an A904 to an A833OD in my slanted '74 Duster and will (a few years down the road) be installing a big block. I'd like to go hydro so I can save myself the hassle of trying to find all the linkage parts and beefing up the Z bar mount so I can use a 10" clutch. My problem is that I don't want to lose the feedback that a mechanical linkage would give me. Though I am more used to driving newer, hydraulic clutch vehicles so I guess it wouldn't be too much of an adjustment for me to get used to a hydro clutch in my Duster.
