671 shift cable conduit size

Does anyone know by chance the size of the brass conduit line the shift cable runs in? Cables are good. Just the conduit is broke. Thanks.

The one I have on the bench measures .250" outside diameter and .220" inside.

I am pretty sure that they are steel not brass. At least they are very resistant to bending.

Mine was brass. Does anyone know where to source the right size tubing to make a new conduit?

Amazon has 1/4" brass tubing - .02" wall thickness which calculates out to .210" inside diameter - my caliper said .220" inside on the original, trying to measure inside a flair with the cable still in the way. Maybe....

I was curious so went out to the shed with a magnet to check the tubing on an original (4000 SOS four banger) and the magnet did not stick at all but the tubing looks like steel so the originals must be a tin plated brass.

There are several grades of steel. Some will be attracted to a magnet while others will not.

Was your measurement at a flared end? I cut mine after it broke to get the fittings off, to reuse, and after chamfering to get the burr off it measures .185. just curious. I got a roll of 1/4" cupro nickel brake line and it measures almost spot on for the .185.
