    86 mustang Louvers

    February 20, 2011

    For 300 bucks (extremely over priced) they feel pretty cheap, they look good but feel like the very thing plastic is going to brake if you look at it too long. Not crazy about the adhesive installation. I have had them for a couple weeks and still can't put them on because its too cold out. Shipping was pretty spot on. Also would have liked some instructions included with the product. I set them on the back window and it does indeed make a nice look to the car. Can't wait for it to stay 60+ degrees some day for 24 hours to put them on.

    A little pricey for the product but really cool! No installation directions but you'll figure it out. Took 30 minutes.

    I was very pleased with the appearance of these louvers right out of the box! I found them easy to install,and best of all- they really look great on my 91 GT. I sprayed mine "fusion" flat black to dull the look a touch, and ive gotten many comments on them. They are very light and no rattles! Thanks American Muscle,see you at the show in Maple Grove.

    The product gives the "Look" that I was hoping for. My 1993 GT needed something to break up the wash of white color. The rear window louvers did the trick. Easy to install. Does not limit your rear vision at all.

    Classic Retro Look

    February 28, 2011

    I'm very picky on what goes on this GT. I always loved the 69/70 Boss with the rear louvers and I decided I wanted that look for my GT. I've owned this GT from day 1 and it has a little over 7k on the clock and is modified. I summited the Blue GT in the images for your review! Only negative it did rattle at high speed a little but a few velcro tabs on the sides fixed that problem!!

    Mustang Louvers

    May 14, 2011

    I love the look of the louvers. It gives my 90 mustang a distinct look and gets the heads turning. I messed up the brackets the first time and the louvers weren't flush. But I got them on now and they look great. I would like to know if they make aluminum louvers or just plastic.

    Old school

    December 24, 2014

    I love the old school look of these. Installation was easy and straight forward, just take your time. You might install a little sealer tape on underside to keep vibration and rattling down. Overall a great product and I highly recommend.
