yes, how you want your truck is entirely your choice, I was just answerin yer question, or maybe askin you to think about it more, especially the "might have been back in the day" part
thinkin about where the truck you describe [basicly stock 4x4 work truck] would have been seen [I was there] in the 50's, when the truck would have been 2-3 years old, and who would have been driving it, I can't imagine seeing one with portholes, anyone with the money to customize that new a vehicle was doing nice cars, the hot item in the late 50's was the 57 Chev and such
now if you were talkin about the late 60's or 70's, and a worn out red oxide beater, saggin in the [censored] that some kid had taken over from dad to impress the crowd at his high school ..... well, in the 70's you could still find those portholed Buicks at any wreckin yard .... so maybe, but I still wouldn't use "subtle" to describe it, nor "period correct" for the 50's
