If it’s not one thing it’s another. Just finished complete rebuild of steering, suspension, brakes….got the new brake booster in and re-installed the drivers seat.

10 miles into the first drive…

I read a few posts about new tachometer cables being too long. One said the correct length was 20.5”

So far I’ve found zip has 24”, Corvette central has 23” and Top flight has 22” - interesting enough the price goes up as the length gets shorter

Does anyone know the true correct length and if they are available anywhere else?

The GM parts books list the '69-'74 cable and casing sheath at 20.66".
You can get replacement cables through general auto parts stores. They are universal cables that are supposed to be cut to length with a square drive tip that is glued on. Use your old one as a length template.

I’m pretty sure my current sheath/cable is one of the too long aftermarket cables. So I’m looking for the entire assembly.

Perhaps going with a good condition used one is the way to go. There are a number of guys offering used parts who may have just what you're looking for - though I can't recommend anyone specifically. Perhaps others here will suggest sources.
