they are one a aspen special wagon http://detroit.craigslist.org/okl/ctd/3028688072.html
the set i have came off of a set of super coupe wheels. the early chrysler road wheels used the same cap 71+. the later cordoba road wheels came with a cap similar to the one you show, where the cap does not wrap the lug nuts, but has a snap on chrome cap 75-77. the cap you have is yet different and appears to missing the snap on lid. i know this because a buddy of mine has a yard full of 71-79 chryslers and i was able to compare. the one you show does not appear to be a mopar cap, but again, i could be wrong.[/QUOTE]
My thoughts also.
