The Crown Vic brakes setup DOES NOT "bolt" to a Ranger.
The Crown Vic even though it has the smaller 28-spline axle shafts
uses the LARGE (explorer) brake mounting flange
the CrownVic/Marquis/Towncar setup differs from the explorer system only in detail
Those details are:
1)The Crown Vic uses what jokingly call a "bikini" dustshield that
protects ONLY the parking brake assembly rather than the full disc
like the Explorer.
2)the Vic setup is IDENTICAL on both sides of the vehicle.
In essence it ses TWO left side assemblies, so that on the
left the caliper is behind thw axle and on the passenger side
it is in front of the axle, this creates what would be a MASSIVE
parking brake cable routing nightmare on a Ranger.
ALL of the "junkyard Easy" brake swaps that have been proposed
have one thing in common, they all require some welding,either to the flange on the axle, NEW flanges on the housing or modiication (redrilling after welding) to the backing plate.
Welding is not "Easy" for most people
"Easy" means 3/8" drive socket set and a prybar.
If you need to weld you may as well weld spring and shock mounts to a complete explorer axle and get the 31-spline axle shafts in the bargain.
