I replied a while ago and have been searching for this thread to update folks here. I received my replacement dash from OPGI after waiting a few years. If I recall correctly, I had placed an order when it was first offered. I have not installed it while I work on front and rear suspension sway bars, installing a Leed Brake rear brake conversion kit, and switching from bench to bucket seats. The first picture shows how my stock pieces fit and match the replacement dash. In the second picture, since someone asked about the dash support structure and I wasn't exactly certain what they were asking, I hope this picture helps answer their question.
I know there are many others who face the same dilemma of a damaged, ugly dash and could use some input on how best to resolve this issue. For me, I considered repairing/refinishing the dash top myself but decided against it simply because of the work/effort required to obtain an acceptable job. Although the OPGI replacement represents a significant budget item, other options, such as having a repair specialist do it, are likely multiple times more expensive. In the end, I figured spending $800+ (including shipping and handling) was the best avenue for me. As I stated somewhere, the dash in our classics is one of the most constant and visible items we look at every time we drive our cars. Hope this helps! And, good luck!
