One of the most important parts of any car's maintenance or restoration is having effective weatherstripping, and your 1971-1973 model Ford Mustang is no different. Without proper weatherstripping, harmful elements such as water and dirt can get into your Mustang, potentially damaging or even ruining its interior. Mac's Auto Parts is happy to present these door window and rear quarters seal kits for your 1971, 1972, 1973 Ford Mustang. Made from the finest weather-resistant extruded sponge rubber, these door window and rear quarter seals feature molded ends to ensure a perfect fit. MAC's carries the finest quality seals made today - from the correctly shaped extrusions, to the permanently bonded corners and pre-installed mounting studs, our seals are the best. Belt weatherstripping is what keeps water and other debris from going down into the door cavity and rusting out the door bottom. After 30+ years of opening and closing the windows these weatherstrips are usually pretty worn out. Get rid of the rattles and stop the leaks - replace them now using our economical kits!As always, remember to trust Mac's Auto Parts for all your restoration needs.
