70 A Body Washer bottle
whats the difference from an original & repro
Thanks

honestly newer plastic. they are exact replica

Why are some pure white, and the same bottle is available in off white, almost a yellow color?

That is so it can look old but still hold fluid, for unrestored cars.

While the attempt to make them aged looking has its merits for an unrestored car, IMO the manufacturer missed the mark a bit, the yellow colored ones are too yellow, and the color is too consistant throughout the part and accordingly, doesnt look natural/correct. Id just go with a white repro, or for an OE car, an NOS one (which usually have a slightly more yellow/aged color as compared to a brand new reproduction). .02

Don't know about the '70 A-body but on the '68 - '69 B-body there are caps that open incorrectly from the originals (back to front). All of the originals have the cap open from the front of the car toward the rear of the car or windshield. The cap's retainer strap is also on the back or windshield side on the originals to open from front to back. When filling an original with windshield washer fluid, standing in front of the car, the cap is not in the way when it pivots toward the rear. Small detail but correct.

I bought one for a 70 Swinger and the holes don't line up with the original. Not sure if it shrunk, or was just made wrong?

Had the same problem with the one I used on my Duster.

Not sure about the off white thing I think the original were white also and just turned color after time. The only reason I think this is.
I had a 69 Valiant that I sold the hood and the car sat outside with the original washer bottle(filled with water fluid), the washer bottle all nasty and yellowed it turn perfectly white after time(months of sitting in the weather and sun) It looked new I could not believe it.

So on repro ones the date codes and all the stampings are correct.
So far just the mounting holes are off on the 70 A bodies ones and on the B body ones the cap opens the wrong way.

The black caps are wrong too. The tops are too flat and the circle pattern like on originals isnt there.

On the 68 to 70 B-Body reproduction washer bottle, the cap opens in the correct direction as they were issued in the 68 to 70 time frame. In the mid 70's, Chrysler over the counter washer bottle had the cap moved to the opposite side. From what I was told, the move was made so that there would be less likely a chance for the lid to be blown open from air disturbance from the radiator or outside air entering into the engine compartment. These bottles were sold in that fashion up through the late 80's. During the mid 80's some bootleg washer bottles did get out of the manufacture with the lid opening in the correct fashion.
The reproduction bottles, no matter the application, do have a date code. Each one has a particular date that does not change, where as assembly line pieces varied on a daily basis.
As mentioned, the original washer bottle lids has a very slight lip that produces a circle pattern about the size of a quarter on the top. The over the counter washer bottles had on the lid, "Washer Fluid" spelled out. Also, on some of the A-Body washer bottles, the over the counter counter bottles are significantly heavier than the originals. So there are some subtle differences as compared to the assembly line to the over the counter to the reproduction piece on all of the different washer bottles.

On my a-body one, the cap also opened the wrong way. They drilled the hole for the cap into the embossed lettering on the bottle. But all appear to be this way, even though it's a Mopar "authentic" part.

B-body washer pump ground ring is also not flared to the housing like the factory ones were.

FYI I bought another 70 a-body washer bottle from Dante's Mopar Parts and it fits the factory fender holes just right.
