64/65 dash gauge cluster

Mine is a little different. 64 Valiant. Were there several variants? Are they interchangeable? My works fine except the speedometer. Big differences in the back...the circled part is not on mine at all, and the arrow shows the ammeter connection on yours, are those wires cut?

Yes- the 64 is different I'll change the ad I believe the gauges are different? Never owned a 64 since 1971.....
