Thanks, Dick...I'll closely check the linkage underneath.
The reason I was concerned re: valve issues is IF I do any driving aside from short bursts on the open road, that stretch from Vegas to V'ville (I-15) is a real killer in the mid-summer. I've had the car for almost 3 years now, & haven't been able to get the time away from work to do any shows, etc aside from a few local events.
I too, LOVE those Crown Coupes! (the yellow body/ black interior colors sold me on the spot!)
