Hi Mike, your Cuda is looking great. I've enjoyed watching the restoration unfold (and come back together again). You mention that your putting the interoir together, including the dash. Question; did you install all the electrical wiring, already? I don't remember the wiring install updates.
From my experience, the wiring was the most frustrating segment of the rebuild. Because the car itself is the ground, keeping the wires in permanent good ground is difficult. My Cuda passed State Inspectoon back in 1998. All the lights, turn signals, horn, etc worked. It didn't take long, though, driving on these bumpy Oklahoma roads that bad connections developed. Chasing down loose connections isn't fun.
Make sure to scrape away some if that gorgeous paint job to make a good ground connection.
Looking forward to more Cuda updates.
Ron.
