This is what I'm looking for as well, have you posted any write ups? What brand/model gauges? Did you have a choice of speedo left and tach right or vise versa? Any resistor wire deletes? Whoever had my car before did a number on the dash wires.
New Vintage USA, they have several models to choose from (I like the 1969 series). http://newvintageusallc.mybigcommerce.com/ You should be able to mount them eather way.
I hear you, digital just doesn't fit the feel of an old car to me. When I saw that on Facebook I was sold. Kind of spendy but the best option I have seen so far short of an instrument panet rework.
Take a look at the link, unfortunately that isn't mine. Should be fairly easy to do but until I step up and buy the gauges I won't be any help.
