None of the shops I talked to seemed to know anything about the shocks, so I decided to play it safe and use the crown vic shocks since they've been proven to work.
I managed to get the sleeve out of the original shock by using a long bolt and a large socket. The only reason I used a socket is that I could find one that was larger than the sleeve, but narrower than the shock. The head of the bolt was the same size as the sleeve, so I pushed it through the sleeve, then through the socket. since the sleeve was able to fit inside the socket, as I cranked the nut down on the bolt, it just pulled the sleeve through the shock.
If I'm too lazy to swap the spacer and isolator around, what problems will I see? I can change them easily on the rear, but I'd rather not take the front apart again.
