Matt was extremely helpful in helping me make sure the right parts were ordered. I wasn't completely sure I picked the right parts, but I emailed them pictures and measurements and he confirmed in under an hour. I placed my order, it shipped the same day and arrived the next. Everything fit perfectly and the windows work like new again- thanks!
