Yea, I saw that. Thats the valving I want. But he hasn't replied... Must of sold them locally.from trail-gear.com
5150 model Bilstein shocks include a fixed external fluid reservoir. Available in 12" and 14" lengths. 255/70 Valving.
For the record my 7100's have the valving stamped on the shock itself. Surprised the 5150's dont.
