Vietnam era (1970) UH-1 Huey cockpit

Didn’t know if I should post here or on the Historic forum…..guess this would be more historic than anything but any help would be appreciated. I’m looking for pictures of an Army Vietnam era Huey cockpit. One that shows the instruments really well. I’ve looked online and have seen everything under the sun but can’t be sure of era/mods…etc. I’m helicopter illiterate and don’t usually do panels of these but have a Vietnam pilot of the 173rd I’m building a display for as a gift. Usually I do WWII but those heroes are all but gone. Any help would be fantastic, pics, manuals, part numbers….particularly of the Air Speed Indicator, RPM, Fuel…and any others. I want it to be period correct for him. As soon as I find out the variant he flew I’ll post it. Thanks in advance.
