1967 - 1970 Manual or power steering OEM factory conversion tips.
The drag links, pitman arms, and idler arms are all specific to manual or power steering suspension systems. Meaning that these three components need to be changed together during a conversion. Another thing to consider, the factory installed 20:1 steering boxes into cars with manual steering. Cougars and Mustangs with the Competition Handling package (sometimes called Improved Performance Option) received the 16:1 ratio steering box which is the same as all 1967-70 cars with factory power steering. On manual steer cars, the 20:1 ratio box requires much less effort to turn the steering wheel, but requires 4-5/8 turns 'lock to lock'. The 16:1 ratio steering box requires considerable more effort but requires only 3-3/4 turns of the wheel - 'lock to lock'. Here is a helpful link for those wanting to troubleshoot power steering problems.
