Service Air Suspension message

[sfsflyer]

My 22 1500 Limited(with 22,000 miles) gave me a Service Air Suspension message . I took it in to the dealer and they found the left rear Spring assembly leaking. New part needed, but apparently this part, MOPAR 68260938AB, is on nationwide backorder. I spent a few hours calling around to dozens of dealerships and the couple dealers that did have it only did so because they had requested it for a customer. Both had said that it took around 6 weeks to receive it. I have also searched all of the online MOPAR parts store with no luck. I am awaiting a call back from RAM Cares to discuss a rental while my truck is out of commission. Does anyone have any recommendations on finding the part? Thanks
