A good way to check is while the engine is at idle check and see if they have vacume on them . The one you want will not have vacume at idle but if you rev it up some it does. from the look of the pic it looks like you could use ether one. but I think the one to use would be ether one on bottem on ether side of the adjustment screw.

That looks similar to my 32/36 except everything is reversed. Mine is hooked up to the one on the top left. I don't have all the other outlets. Just the one for distributor advance. I'm not sure what all the other ones are for.
