I'm also interested. I've not seen any ready made ones. Most of the installs I've seen use a modified A/C bracket to mount the P/S pump low on the driver side. I want it all, A/C, P/S & alternator. So I haven't figured out an approach yet. One that looks promising is to mount a spacer under the thermostat housing on the front of the block and use that as an anchor point for a passenger side A/C mount. There's a boss on the head that could be drilled and tapped to supply a back attachment point, or the side motor mount boss might work.
But all I've got to offer is some ideas, no hard parts.

Leon
