Hello To All The Chrysler Fans

Here is a trivia question I have that maybe someone can solve for me.  I
have three unopened small Mopar Bags that I was wondering if someone could
tell me what they fit.  All three bags look to have the same piece in them.
Here they are:

Bag 1 - has two lines of numbers:

line one:  1 3514 168
line two:  74455 0389

Bag 2 - has two lines of numbers:

line one:  1 3514 168
line two:  74455 1189

Bag 3 has one line of numbers

1 3514 168 PP KU

The little piece is round, larger than a quarter and has two hookups on one
side and one on the other side (look like small rubber hoses slides over
them).  The side that has the two pices sticking out also has a small grey
round piece of foam.

Any ideas what car or trucks these fit?????

Thanks
