Yes, there are two 91-93 shocks in my inventory.
Are you volunteering to pull them apart and reassemble them to get shim stack info?
If so I'll order up a couple of seal heads and have you swap them out while your in there
In fact, I have many other shocks I could send you so you can get the shim stack info.
Good call on calling Pro Action.
They may not mind giving out the stock shock shim stack info.
