where do these washers go?

[richRTSE]

trying to sort out a few boxes of nuts and bolts and can't remember where these washers go...they are about 1-1/4" with a 3/8" hole and about 3/16" thick. They came off either my 69 or 70 Charger....anyone know where they go???

Pretty sure those are the strut bar washers they are rounded on one side just like yours...

At 1-1/4" in diameter they are too small to be strut bar washers.

I was going to say fender body shims, because Mopars used round washer type ones vs the square type. But if they were body shims they would be painted.

Next best guess is for the heater box as others have replied, but like A383Wing I don't recall them either.

Thanks for all the replies. I don't remember if they ever had paint on them, I've just been running batches of nuts and bolts threw the parts tumbler and that's what they looked like after they came out. I was thinking they might be body shims for the front fenders, but now I believe they are for the a/c heater box...and that would also explain why there are five of them. I took the car apart over 12 years ago and my memory is a little faded...I'm guessing this may not be my last "what's this part?" question...

I have my heater box out now.  There are 5 studs that go thru the firewall. 
They all have 1" dia metal washers on the Box side and I believe they are followed by a soft washer before the go thru the firewall.

I had those on my AC heater box...
