Source for missing relays under dash

[76orangewagon]

I've started tearing apart the dash in my 1971 Cuda for restoration and noticed that I have a couple empty relay holders one mounted to the side of the Brake pedal support bracket and the other on the side of the ashtray mounting bracket. From the research I have done it seems one is for the 4 way flasher (brake bracket) and the other is "possibly" for turn signals (ashtray bracket) but I can't seem to find a source for OEM rectangular style to use in the mounting brackets since they are both missing. Is there a good source for the OEM rectangular style around ?  Any help would greatly be appreciated.

Those round flashers plug right into the brakes....  And while they may look like a relay they are definitely not relays..

They were round from the factory

I wasn't sure if they were buzzers or not and just assumed it was a replacement relay..my mistake, that being said an I correct in assuming that the empty brackets are definitely for some type of relays and if so where can I source them from ???

Again, the round T/S washers go into those clips/brackets...

Ok I think I got it now ...the round flasher would mount sideways into the rectangular bracket. I was under the assumption that I needed something that would fit in the bracket like the one in the picture.

While I sure don't know for a fact but I think some were rectangle. This is one that was on my 71 when I took it apart. Original? It fits the bracket perfect.

Shane...that's what I assumed I was looking for, but I'm no expert in wiring and you know what happens when you assume.

[Shane Kelley]

Oh yea. When I was building mine I was looking for the same ones also. The that came in my car is exactly like the one in your picture.

Taken from a funny angle but..

So this is factory correct ? It fits fine just reminds me of a round peg in a square hole

Just how they were.... The square flashers are interchangeable but when I first worked on these cars starting around 74-75 90% had round flashers, I believe the boxy ones were replacement parts....

[Shane Kelley]

That's how they go. I agree that it does seem odd.

Did you purchase your car brand new ?

Don't know to many 5 year olds buying new 71 Cuda's. So that would be a BIG no!
That's why there is this (?) behind the word (Original). I was wondering if some cars could have possibly came with the rectangle flashers. Early, later or superseded kind of thing. Let me ask you this. Can you say positively for a fact none ever drove off the lot with them?
I will say this. I have restored several makes and models of cars over the years I had never seen the rectangle flashers before these last couple Mopars I have done.
