Front suspension options

Have you compared the track width between the two.
A crown Vic engine should bolt right over that.

Track width is too wide in it's stock form. Like JD mentions below, sectioning the crossmember, and shortening the rack, would both be necessary along with minimum 17" wheels. No Ford engine going in. However, a 200R4 trans probably will eventually!

If you could section the Crown Vic to get your track width right, and use a shorter rack, that might be your cheapest option. I'm using the HDK Coilover conversion for stock steering and k frame. I understand how that may not be a good option for you if you want rid of the rear steer. If I ever find the right 57 Dodge pickup.....the Crown Vic WILL be my front suspension choice! Good luck.

Sectioning and shortening. That was what I was thinking. Someone over at the Jalopy Journal has done it with success so I know it can be done. BTW, thanks for the positive response!
