Are these repo door vent window plugs accurate? The original ones I recall having on past cars were just simple push in rubber plugs that were only slightly convex on top, and they had a smooth finish with no clips/steps of the sides to hold them in place.

Those are incorrect.
Factory plugs were smooth, molded in colors to match the UDF, and came to a shallow point.
It's not right that Classic infers that theirs are correct

Incorrect and too much $$$ as well. They are not the only place selling those either.

Yeah, not even close

The plug from a black Bic pen is better than that and you get a pen LOL

I found dozens of them under a carpet it a 69 Dart I parted out, mostly red and green! Someone must have tipped over the bucket they were in and decided it wasn't worth the time to pick them a up and just installed the carpet over them...LOL..

Anyone have a close up picture of an original?

i thought Dante has the correct rubber ones

Nope - his illustration when you get to the actual part shows the same rounded & grained plug.

I found my container with them in it today, I will take a couple pics, forgot to pick it up from my shop and won't be there again until Thursday.
