Well, that's almost like a favor isn´t it :) Maybe you can returen it by asking Mr. Arnew about the rear shocks. The front shocks are often referred to as 90/10, I suppose that´s fine...
The NOS 1970 Imperial Shocks I have are more like 10/90. I would like them to more towards 50/50, but that do a Pro say?
Thanks, Stefan
