Power steering conversion

I converted my 69. Since your 70 has biscuit motor mounts like the 69, the high pressure line of a Saginaw box can interfere with the K Frame. The brackets sold by CVF lift the pump a little and allow it to clear. As stated you'll need the box, pump with brackets, high pressure line & return, and the proper power column or power shaft. I converted for a faster ratio and had the box rebuilt by Firm Feel and used a low pressure pump for rack and pinions to rid the over assisted feel of the stock set up.
