Is the upside down # to the right 1608?? If so then I'm confused Chrysler used 3 digit in 61-9 Example 349 would be 34th. week of 1969.
Also if you need wiring you have to go through Year One or Classic since M+H doesn't sell direct for Mopar.
I used to buy these with electronic guts and then buy an NOS and swap covers.

Hope some of this helped
