Wanted to provide two updates for those who are following:

First I ended up taking it to a shop for the convertible top problem. They easily diagnosed that the trunk latch wasn’t reporting that it was locked. They took apart the latch and found the wire had come apart. Fixed the wire and everything is working perfectly. THANK YOU to everyone who tried to help - this forum is great!

Second is that a member here has agreed to purchase the car. We’ll finalize the deal in the next week and it’ll be shipping to Florida for the next chapter in its hopefully very long life. It was very important to my deceased friend that the car go to someone who knew about and loved the SRT6. I feel good about that with the new owner.
