FinishLine sells a slave cylinder kit which mounts the cylinder on a bracket and the bracket to the block/bellhousing interface. It's clean and compact. It's also $175.
I didn't purchase the kit, but I duplicated it with some 1/4" flat stock, a slave cylinder from NAPA, and an afternoon of cutting, shaping, and fitting. Total cost was about $75, including stainless fasteners.
Instead of the mockup drill bit you see here, I purchased a CNC pushrod ($13, I think) and cut it down to size.
