As mentioned I'm in the auto/truck windshield biz and would highly recommend NOT using Safe-Lite. Despite the semi-positive comments in this forum they're typically on the lower side of quality both in the stuff they install--they manufacture their own parts--and their installers who are trained in-house by Safe-Lite----they have little to no experience with any one particular vehicle especially "older" vehicles like our vans.
(Obviously I'm not in your market area so have no financial stake in this--simply trying to get you the best end result.)
One example of that limited experience is IF your vehicle has ANY visible rust of ANY degree they'll walk away from the job, tell you to get that completely fixed first and then they'll return. If they begin the job IF they find ANY rust under the windshield in the pinch weld area they'll walk away on that too---same speil, get it fixed and they'll come back another time, no charge at that time.
Independent shops understand small bits of rust could be present and are completely ready to make the small repair and add future prevention of such things. Its not a complicated process but Safe-Lite chooses to put customers into inconvenient situations without concern for the problems that might create.
Further independent shops will have enough experience with E-Series vans so they'd know to pay special attention to the upper corners where a factory body seam exists---this seam has been known to pull apart and cause a leak. Sadly too often those leaks go undetected resulting in hidden rust under interior trim panels and floor coverings.
Safe-Lite's slick TV and radio ads are nothing more than scare tactics designed to worry the bejesus out of soccer moms that their kids are in grave danger of beheading if Safe-Lite doesn't send their crack squad of "technicians" out to immediately take care of things. Balderdash in the real world yet it seems to work on the uninformed. No offense to soccer moms intended.......
While they are quick to respond to problems--NEVER the same tech returning BTW--its better having it done correctly the first time. Safe-Lite does not deliver that consistently.
The ONLY advantage to Safe-Lite is they have nation-wide service in the event you had an issue while away from home. However their quality is still inconsistent no matter where they're located. If you're paying for replacement out of your own pocket you'll find them higher priced than
As said "factory" windshields don't exist although you can choose a Carlite brand which is close to what was installed during manufacture. They do carry a premium price for no reason other than the name. I use that brand because I remove the rear view mirror lug and can order a part that leaves a "clean" without that annoy bit of schmutz distracting me. The windshield most shops would bring would not give them finished result but if you use or keep the rear view mirror it would be fine. Obviously I don't have or use the interior rear view mirror.
Brand wise you'd want to stick with PGW or Pilkington. Do know Pilkington has a secondary brand known as Tri-Val which by their own admission "isn't the worst stuff out there..." Yeah that's what we want right?
One last thing---windshields come in "colors" that have been dependent on the year of the van---at least that's the way its supposed to be. These days most shops use a part number that fits all E-Series from 2013 EOL back to 1992---its easier for them to inventory. While the windshields fit perfectly there are minor differences that can be obtained or omitted depending on your personal preference.
The least expensive for the shop to buy is what we call "shaded"---the dark band of color across the top, p/n DW1504 GBY in Carlite or another brand. The W/S withOUT that dark band is DW1504 GTY--it carries an increased cost to the shop of about 25%. FWIW this is because more of the GBY's are made than the GTY's so economy of scale figures in.
(Please know those numbers are for illustration only---can change depending on a few factors like the rear view mirror bracket I mentioned above.)
In the end take whatever opinions and/or experiences you feel most comfortable as they apply to people working on your van or the parts they use. Additionally if I can be of further information or help don't hesitate to PM me or post here---glad to do what I can.
