For what it is worth, I've learned to check the thickness of any pad you might buy after you install them. The thickness might seem correct, but it is common for the pads sold today to compress more under weight/time and the worst problem is they can allow your cab to contact your frame over on the passenger side. If that occurs, you'll get a lot more noise from your frame transmitted to your cab than you should. One way to fix it: go to a plumbing supply store and purchase a bit of shower liner material (it isn't expensive and they'll probably sell you 1 foot by 5 or 6 feet). It is about 1/16" thick, pvc based and wears like iron. Won't compress at all but will deaden vibration noise very well. Add this to those pads you bought until your cab doesn't touch the frame and actually if you want, you can make a complete pad by using the special glue sold for the shower liner sheet and laminating it. Use a hammer punch cutter for the holes and cut the hole for each piece separately. I've done this and it worked very well. You can also use this to make the pads between your front fenders and inner fenders and other mounting pads used in your front end. It is better than what is sold today because unlike cellular rubber, it will not absorb water. Good luck.
