You can ask Davesduda if he has another one, but I believe he told me I bought his last one.
Not sure who else might have an NOS one. You could try Brad's, Len Dawson's Deception Pass and I believe a company in Canada (have to find the name for sure, but think it is called National Mopar Parts). Thos usually have some of the more hard to find NOS items.
If you want to go repop, I believe I got mine from Layson's, but would have to check my records.
Hope that helps..
