Power Steering Conversion Kit
for Ford Mustang 1968-1970

Manufactured by Borgeson | Part #999021

borgeson logo

1968-1970 Mustang complete 14:1 quick ratio power steering conversion kit. 

Fits 68-70 Mustangs with manual steering and 289/302/351W.

Includes all necessary components for conversion.

Borgeson offers modern integral power steering conversions for 1965-1970 classic Mustangs. The Borgeson conversion box is a new manufactured modern integral power steering gearbox. The Borgeson integral power steering gearbox provides true modern power steering feel, feedback and a quick 14:1 ratio. Borgeson has manufactured this box to bolt directly to the factory mounting location and to fit the stock pitman arm. The column will need to be collapsed or shortened for clearance of conversion box. (Details below)

All Borgeson power steering boxes and pumps are assembled and tested in the USA from globally sourced components.


1968-1970 Cars have a factory collapsible steering column. Gently tap on the rag joint flange with a rubber mallet to collapse the shaft in on itself for the needed clearance. Conversion box will then connect to column with half rag joint #990016 (Included).

NOTE: Will not fit with factory Z-Bar clutch linkage. 
NOTE: Requires 2-Row crank pulley not included. Click Here: 2-Row Replacement
