For what you are trying to do I would look for a combo headlamp/cluster dimmer switch and a matching 2 speed wiper. Something retro. That will leave you with an empty hole but I drove my 73 Challenger like that for ten years and it never bothered me. 73-76 a-body should work if you can find them cheap enough but there are probably other options out there (headlamp looks to be the same/similar to what's in the Rockauto link but you'd still need a knob/shaft) . My only concern would be things getting too crowded with the flared a-body knobs, might just have to try and see.
