Usually in the dash with a cable. I actually have a box of new 5" tachs for them. Have seen column mounted also.
Now cables are a PIA to find in the right length, no universals that I have found yet that you can cut down. View attachment 1715444611View attachment 1715444612
Not surprised... Is it same ends as a speedo cable? Tough to find them even in right length. Most are way longer than needed. I got mine from NAPA. Think its just a little longer than original.
