Everyone was swearing by DDM on my other thread when I asked what would be best, but I will definitely not be purchasing from them.
Hope everything works out for you
That's because DDM used to be decent quality kits. Their quality control has tanked lately, though, big time. I have a kit on a car I sold before I got my Denali that still work (sold the car to a friend, so I still see it). They are in their 7th or 8th year now with no problems. Now it seems like you're lucky if you get a kit and both sides work, which is just not acceptable.
Couple that with shipping direct from China, crushed packages that can sometimes get "lost" along the way and take weeks to get to you...it's really not worth saving a few bucks on the risk that they might work.
I used to be a big fan of DDM and referred a lot of people to them. I don't anymore.
