hydraulic clutch in A body

I know there have been several setups shown and discussed on this forum before. You'd have to do a little digging to find them, but generally a search for "hydraulic clutch" would get you pretty close. I think someone did a push style setup with a Toyota slave if I recall in the past as it was the cheapest easiest one he could get a hold of. I think the pull types are maybe a little more common as a retrofit since they're usually a little easier to work our mounting for. You have to have a pretty compact slave as I recall to fit in front of the clutch fork and around exhaust.
