This Borgeson integral power steering conversion upgrades a manually-steered classic Mustang to a modern power steering feel with a sporty 14:1 ratio. The kit bolts directly to the factory mounting location and fits the stock pitman arm without shock tower modification, though the factory column will need to be collapsed 1-2in. for clearance.
