I pull a crown vic front end out of the local pick n pull and swap it under the old 1969 F100. Use a Back Yard Customz kit to box the front frame and weld it all in place.
Front suspension can be used from the following vehicles: 2003-09 Crown Vic, Grand Marquis, or Lincoln town car. OR a 2003 -2011 crown vic police interceptor.
