[71 super]

The precision gaskets are hit and miss- the problem I believe is the repop trim. case in hand, I used 67-70 precision gasket, let it get warm in sun and use OEM windshield- went in with one try- this was my first windshield ever! #2 Again precision but used repop 71-72 trim- trim was twisted and would not stay in the channel once the glass was started. I purchased a set of 67-70 trim (precision brand and the correct precision gasket for the year trim) and it too went right in. By now thinking I have the cat by the tail. But in the words of Mark twain "a man hold a cat by the tail is about to learn a lesson the only way he can" . I went to install windshield in 71 red and white truck, I used trim purchased from truck shop- counter part sh*t and the corresponding gasket again counterpart sh*t, trim would not lay flat,looked like crap and put the windshield in a bind enough to crack the thin aftermarket glass. On to round two, bought rubber and trim for 67-70 and another glass, the seal was precision but the trim was another brand. Seal fit well trim fit like crap but better than the counterpart stuff and the glass is in. The reason for bunching of the trim is from being slightly off center. Some stock trucks were the same way. My 4x4 did not bunch, my bb truck was bunched innitialy and settled out, the 68 never bunched at all and the red/white 71 bunched in both upper corners. My advice - use precision gasket and either OEM trim or if you must use Precision trim, everything els is purely a waste of money and nothing more than scrap. Another piece of advice use the 67-70 version of both as the lip is deeper and is easier to seat than the shallow 71-72 trim and it seems to be more forgiving as well. Good Luck.
