i have installed 3 of these all on 70 cudas, like any other remanufactured part you may or may not have any issues, what i have found it the under layment foam needs to be trimmed or cut away around the cluster area, because of the way these are made the vinyl needs to be trimmed in the light bar area and thats about it. since these are redone on original steel core fitment really isnt an issue. they stand behind there product with any QC issues. I inspect every dash that comes in to us for stock for any visible damage ( fabulous ups ) or flaws in the vacuum forming. i will be putting one of these into my 71 cuda when finished, i would not hesitate to sell or use them. if they were not a good product i would not sell them.
hope this answers some questions.
