After a brief search I didn't find this specific topic.. so pardon the repeat if so.
I have 94 GT and have the ability to swap out a Dash Cluster with a 97 and want to know if the 5.0 to 4.6 changed it enough that the swap will not work.
Here are some detailed photos of the back of the 94-95 clusters and 96-98 clusters. The back circuit boards are different or upgraded as you can plainly see.. but will it plug and work?
