you know, your time is money/valuable. it's going to take you a couple hours to get another set off another axle or cutting the currents ones off to remount. trust me, do yourself a HUGE favor: cut those things off as quick as possible, grind it down smoothly and spend the $18 at your local ford dealer for new perches.
almost everything you need for this swap can be bought for decent prices at your local dealer and through your local autoparts store. i spent almost $165 for everything including shock mounts, spring perches, 1330 flange, 1310/1330 u-joint, ALL new brakelines (hard lines, junction, OEM soft lines to calipers including brackets, etc..), flange bolts, grinding the rotors, paint, custom u-bolts, etc... this is not an expensive swap by anymeans. if you're looking to get everything from one place and not willing to do the footwork, that's where the price goes crazy. take your time, spend a few days doing your homework & gathering parts and this swap can be very cost effective.
