80-90% of the 914s came to the USA with tinted glass (heat resistant IIRC is what the PET manual calls it in transliterated German to English).
Your in TX - IIRC it gets stinking hot there, & sunny & bright, & lotsa UV to damage the interior.
IMHO - go with tinted.
Prosource is one source & possibly less expensive than Porsche, but the dealers still sell the clear & possibly heat resistant/tinted (it won't have the green band at the top) - but not cheap.
Go to the Porsche website, Classics tab to that area, & look up for documents on that page, select for 914, & downloads yourself a FREE pdf PET 914 factory parts manual! Great reference & did I say it was free!?
You can get both types of 914 windshield part numbers from it, then try Suncoast (FL) or Sunset (OR) Porsche dealers for their best pricing + Shipping (they seem to have the best discounted pricing).
I have a 1980 PPG windshield with the greenband from an old insurance replacement in my 73 2L, & it served me well in Sunny SoCal & Desert Southwest back in the day, & it helped with the heat & glare. Plus my car was equipped with "Tinted All Around" option from the factory - so clear wouldn't make sense for my 914 resto.
BTW - the rear glass was never tinted from the factory, since it's shaded by the roll-bar & backsloped - ergo totally unnecessary due to it's good design thinking!
So the Prosource glass shouldn't scare you off due to the green band, but check with others on here about whether it's a proper fitment, cuz I've seen complaints on here about some of the aftermarket windshields.
If you're looking for absolute Concours CW correct - then go with the Porsche part, but realistically you won't get dinged for the other in a PCA Concours locally (maybe in Parade if a tie & they start looking for non-OE parts as a tiebreaker).
Good Luck!
