I did not get a chance to measure yesterday, but I will do so tonight. The only additional parts you need is one spring and one spring retainer washer (see silver retainer washer at top of the two front shocks) for the smaller rear track shock.
What are the chances that you have the front shocks and springs still. Being as we have had no snow all year the seals have gone out on my WE now that we do. I am desperately seeking to get my dragon back on the snow and I refuse to pay $900 for a third set of WE shocks. I would love to get these asap. thanks! give a call at 2087550417 if you have these still available.
