All three of my lumbar air bladders had ruptured. After many unsuccessful searches for the OEM ISRI part I remembered that I had a set of air wedges in my shop that I had purchased on Amazon a while ago. I was able to attach them with cable ties in a stacked manner in the original three positions. I’d did add some additional silicone vacuum tubing to allow the lines to “sweep” more back to the control valves to avoid kinking the lines. So far so good and they can handle much more pressure and abuse than the original air bladders. Safe travels friends…
