70 Nova TCS Relay

[Nova Research Project]

Marlin,

At the local Ace hardware I found some aluminum rivets and steel washers the correct size for the TCS relay. They are made by Hillman of Cincinnati. The Rivet is a 3/16" dia. x 1/4" tube rivet with a 3/8" head # 1278M. The steel plated washer was a 1/8" #8 #1235-A. The hole will need to be drilled out to 3/16". I wonder if they make a steel version of the rivets. They also had a Hollow Steel Punch made by General for punching the holes in the plastic for the relay.

I have a few questions. The many year old Softseal wire channel I have is much stiffer and slightly different shape. Not much but a little. Have you bought yours yet? If so how does it compare? Was your original relay installed through the existing holes or punched through the plastic? See attached photo.

Lastly was you relay number 3961573? Today I realized that they are date coded. What was the date code on yours? My replacement is 4-0 (April 70), My original was dated 12-9 (December 69). Looks like I need to find an earlier dated unit. Thanks, Greg
