P/S Conversion 65-79 Mopar 1-1/4" Sector Shaft

Borgeson has now developed a modern power steering box for the 1965-1979 Mopars. This box fits both factory power & manual steering cars. The Borgeson conversion box offers a 14:1 quick ratio, firm modern power steering feel, drastically increased header clearance and a 10# weight savings over a factory power box. This box bolts directly to the stock K-member mounting location and fits the original 1-1/4” pitman arm. The steering column will need to be shortened for installation of this conversion box. Use of a power steering cooler is highly recommended in these applications.
NOTE: This box will fit all original Mopar 1-1/4” pitman shafts. If you car has the smaller 1-1/8” pitman shaft you will need to purchase part #800126.

The original steering column shaft will need to be cut and shortened for installation. Connection to the box is then made by drilling and pinning our #036425 Mopar vibration reducing universal joint coupling to the shortened steering column shaft. Drill bit and pins included with coupler.
