I am happy to report I received the dash from Jamack yesterday! It was shipped to my nearest Greyhound terminal so I had to drive 65 miles to get it but it was worth it. It did have some small undisclosed issues but none of them were deal-breakers. When I told John about the issues, he said he was unaware of them and immediately offered a refund. I declined. In the end, I am happy. John kept his word to complete the transaction with me even though the eBay transaction was previously canceled.
For any of you that still have unresolved transactions with Jamack, I urge you to contact him to work things out. It seems to me he wants to do the right thing on deals that may not have been completed successfully.
Although this wasn't the ideal transaction, it ended well. I got a rare part at a great price. Would I do business with Jamack again? Yes, I would. In fact, I plan to purchase something else from him as soon as he gets home from his current trip.
I have attached some pics of the dash. The vent in the images did not come with the dash, I was just checking fitment of the vents we did a
group buy on a few months back. They fit perfectly BTW!
