70 Nova TCS Relay

[SS427]

I went and looked at a '70 original mileage Chevelle today and it had these plastic rivets in the gutter. This car was a September Van Nuys car and is almost 100% original excluding plug wires, water pump and radiator (bird). I have never seen these on the Chevelles before. Ron and others have stated they had these on their Nova's. Anyone else seen this type of rivet?

Was this Chevelle in Michigan?
Is it Astro blue?

I took off the complete wiring harness from an untouched 70 L78 Nova, including the wiring gutter w/ TCS switch attached. It is attached with those exact plastic push rivets. Does an original TCS switch have "littlefuse" stamped on the cover.???

JRSully,

"LITTELFUSE" stamped on the cover is correct for the one like I posted. Any chance of a picture for the research project? Any idea of the date code from the trim tag on that L78 Nova? I am tracking VIN and Body tag info. It would also help track when they may have started using the plugs.

If anyone else runs across any Novas (68-72) in the boneyards, would you mind grabing the VIN and everything off of the trim tag. Pic's are cool too. [img]/ubbthreads/images/icons/grin.gif[/img]

Thanks,

Rick,
I got my plugs sitting in front of me here as I type and they look exactly like those you posted a picture of. They were on my car when I bought it from the original owner but I figured somebody replaced the rivets at one time. Now I'm glad I hung onto them. Also Rick, I think they may be the same plugs that are used to hold the flap for the radiator to the radiator support on BB 70 Novas. It looks about the same size but I can't remember if the cars I've seen had ones like that with the line that runs across the center of it?? It could be one and the same thing!!

Sully,
The wording says "little fuse inc" at the bottom. There are two styles of this TCS if I remember correctly. The style shown in that picture is a different one than mine. Mine also has a date above and to the right of the little fuse inc wording.

Ron,

I agree that the plug looks the same as on the BB radiator seal. The radiator seal plug is also the same plug that is used to hold the grille to bumper filler to the steel reinforcement on the Nova. The picture I sent you was of part number 9792217 (attached). The short one is the original off of my bumper filler. The long one is the newer version I bought in a bag of 25 or so several years ago.

The plug 3952914 was used on the 69 Nova filler. In the 70 Nova model year 9792217 replaced 3952914 in December 69 on the filler. 9792217 and 3943268 were both used on the 69 and 70 radiator seal back and forth.

9792217 was shown in the 69 Camaro AM possibly as a replacement for the inner fender seal staples, but was removed on July 2, 68. I wonder if this plug was used anywhere else on the Monte/Chevelle?

Despite the TCS relay going back and forth between the two part numbers, I find no reference to plugs to install it. I wonder if this was done on the line because it was easier than the rivets?
