RTSE,
when you tried the 1-3/4 headers you had F.F fast ratio arms on?

If so could you tell me which one's worked for you, and these were above the steering link type correct?

FYI I spoke to a tech guy at Pertronix (dougs) and he said no-way they would fit. that they barely fit a normal pitman /idler arm.
But you know how it is with tech guys on the phone.....
