Ran this in my turbo RX-8 for a year before switching gearboxes. It's an off-the-shelf driveshaft, available at Jegs or Summit among other places. P/n 188442. Typically around $450. It uses 1310 u-joints. Perfect condition, just no use for it. Hopefully someone here can use it in a challenge car or another project. Asking $250 for it, will ship. E-mail if interested.
