wanted: nth sliders

[altierior]

i want to protect the u-joint and yoke on the vulnerable pinion end of my driveshafts. the nth degree sliders are the best solution i have seen. yes, i know that they have sold their inventory and operation to AEV. but AEV is not currently offering the sliders i need, which are for the XJ high-pinion Dana 30 and the Chrysler 8.25.

does anyone know of a vendor who might have old inventory? or better yet, does anyone have either of these to sell?
