Hi,
I'm upgrading my front suspension to some oil shocks and I have to remove the valve in the original shocks but I'm not quite sure where it's located.
The valve is located under the 23/32" A/F headed plug at the bottom inner side of the damper.
Remove the valves making sure that you have all the small washers. Drain out the old oil and replace with engine oil. The dampers then act only as the top suspension arm.
