Nova TCS Switch & Wiring Gutter 101

[Nova Research Project]

Hello,

Here is a short set of pictures that details the Nova TCS Switch, Wiring Gutter and the Rivets that fasten them together.

This first sections covers the small TCS switch 3961573. I do not have a large one yet. This style switch was interchanged with the larger 3983958 switch. I have not figured when they were switched or when or why they were screwed to the firewall. Click here to see the other attachements styles.

The first picture shows two OEM gutters compared to the two available reproductions. The reproductions do not have the holes punched in them. The holes can be punched with a leather punch, the same goes for the radio ground slot, just use a buckle punch.

Note the curve in the OEM gutters and the corners in the reproductions.


Here is a close up of the switch and the rivets. The switch on the left was media blasted and is bare metal. The one on the right is the original cad plating with the rust patina.

The left one was riveted in the holes exactly. The right one is the typical mispunched installation. Note the plastic still in the tubular rivet.

The switches are also date coded. The right one dated 12-9 was installed the 2nd week of January 1970.



Here are close ups of the OEM rivets and the replacement rivet and washer. the washer ID is a bit small and needs to be drilled out to fit on the rivet.



Here is a large picture of the TCS rivets and washers.
