I've had this laying around for awhile...I'll never use it. I'm looking for opinions on if it is a genuine Mopar unit, or some junk aftermarket unit. The 845 stamped in it is last 3 digits of Chrysler part number 3420845. The construction of the unit is almost spot on in comparison to a NOS Mexican 68-70 B- body unit I have that dates from 8/2000.
