Finished! Brutal 'Cuda

If you used the yellow contact cement that comes in a metal can. Quart paint can not the aerosol type.
It will hold up and remain stable for many decades as long as it doesn't get wet. It does cure and is unaffected by heat.
If you used the aerosol spray trim adhesive it is formulated to never cure giving it the needed shelf life and ability to to be sprayed from the cans nozzle. Good marketable product but bad for a trim project that is subjected to heat. Particularly when gravity is opposing it remaining in place.
You should be OK on your dash pad if you used the aerosol trim adhesive as it is wrapped and clamped after being bolted in place. It can blister if it gets very hot due to the non cure formula though and may need to be repeatedly pressed back down flat.
Your work on the pad turned out great and you are remarkably skilled to get such results on your first dash. I am quite impressed. The A body pad is an easy one but I know how difficult dashes can be. As the owner of an upholstery shop. I have never been able to teach dash pads to employee's with good results.
Just as impressive is the styling and execution fabing up the rear spoiler. Like it a lot. All barracudas should have came with them from the factory.
You got this car building art form mastered.
