The lower control arm for the Crown Vic is not the same as a mustang II control arm. I have never seen a mustang II control arm anything like the 03 + crown vic lower control arm. So i highly doubt you will find a cross member with the right style mount for the crown vic arms. and judging by the looks, the lower control arm on the Crown Vic take the brunt of the work for the front suspension while the upper control arm is more of a guide than load bearing.

The Mustang II crossmember on Speedway does not include the lower control arm pivot tubes are not included, but are needed to mount mustang 2 style lower control arms. You may be able to modify it to mount the CV arms... it will take some fabbing skills.

In the end I personally think it will still cost more than fabbing your own crossmember based on the Crown Vic out of steel.
