Have been trying to locate coupler (The box like one with roll pins; P/N 3579522) for months to no avail. All local dealers have item on backorder (approx 100 orders) so it must be nationwide. Does anyone know of another source for this part??
Thanks

 

Best alternative is a shaft kit with Borgeson U-joints. Give these guys a call. http://www.hotrodssuperstore.com/19to19dodtru.html These are for pickups, but you might shorten it some. Phone# at the bottom of the page.
