Check the length of the pitman arm, and see if there is an idler from a bigger bodied car the same length. I put a fast ratio pitman arm on my Challenger, with a PS box. I knew it would do the wopsided turn one way farther than the other thing, so I had a buddy that worked at the parts house look thru the books to see if we could match an idler arm. He found one off of either a later B body like a Cordoba, or a C body. Snatched one off the shelf and it was the same length as the fast ratio pitman arm. This was all back in 90 or 91. If I had it to do over again, I would have left it alone on a PS car. As twitchy as Chrysler PS is anyway....with the longer pitman and idler, you can look at the steering wheel and be half way in the ditch if you ain't watching what you're doing! I'm not sure how it would act on a manual steering car? You might also check to see if anybody makes a longer idler arm for a 67 A body, and see how the length matches up. I think 67 is the only year of later A's that have the same style idler arm bracket as early A's. Maybe that would work if you're lucky enough for them to be available.
