Well Steve, it´s a good guess.
Yoy are probably in the correct way, I have been checking my Uniform and it´s more than probably it´s that suit.
Here is the trousers
Here is the jacket
There is also a helmet cover, but I haven´t photographed it yet.
Notice the waist metal hooks for belt, just a reminiscence with german WWII jackets, of course the dot pattern does to.
When Ezapac was born in 1946 it was made in a nearly imitation of what was the German parachoutist assault group in WWII (remember the afinity with Germany during that time)
Sometimes the information given by by family is mistaken or disolved in time.
I put 2 links of videos of Ezapac in 1968, you can see there both dot uniforms used by them

Otherwise about your uniform Steve, I would like to know if that arm patch came with it, It´looks like a so actual one for that uniform. Plastic models were used in late 70´s-early 80´s.
Going back to history of this "dot uniform", even it´s always called like the EZAPAC one, in Spain we lived a time of almost poverty, so equipment was not a priority. Talkint to veterans I was told most of the camos uniforms were used just for a couple of times during the military service, most times used when needed to show population an special image of army, like this photo where this dot uniform was given to DAC Brunete nº1 (Cavalry)in 1964 in a Victory Parade just for that day (never more given, just for that Parade)
There is also evidence of it´s use by Mountain troops.
Going inside legend, somebody told me, that an officer has told him that those uniforms had been made for Portuguese colonies by a Spanish factory but they were desestimated because of it´s thick manufacturation (not good for hot weather), so Spanish army bought them in low cost (perhaps this thick manufacturation made them appropiate for paras and mountain troops, and of course for photo situations, loool)
Anyway this is legend, so no possibility to be sure of that.
Changing to other thing, dear Steve, US had not bad relationships with Spain at that moment at all, in fact, without forgetting the fascist reeminiscence of Franco, the current problem of the cold war werw soviets, and Spain had not a good relation to them at all.
Spain received a lot of help from the US (economic and military) at that time with the European Recovery Program, which was made to control comunists. So Spain allowed American Military bases were installed in Spanish territory like a cooperation defense treatment.
Here you have a photo of a combat exercises between Americans and Spanish during the 60´s. (Spanish force is formed by paras (black berets and mountain troops). It´s a curiosity that mountait troopers don´t wear camo cap, althoug it exists, so is more than probably that this short jacket uniform was just recently given to the mountain troops for that exercise.
Well lots of things to talk about uniformity and history, but my English is so poor that I spend so much time to say less than a half that I wanted.
Thanks you all for the reply and specially Steve, who I think is good in Spanish uniforms
Best regards and sorry for this kind of heavy block I wrote ((I dont work these days
