1969 Dart Pro touring daily driver **Crashed**
So the 67 K member idler mount issue was a surprise that delayed things and took much longer than expected. In the end the jig was scrapped and I got help from my dads friend who is very experienced and has built many cars.
We spent a lot of time measuring and making small adjustments in order to locate where the idler mount should be. The idea was to mirror the position and motion of the pitman arm on the other side of the k member. We also learned that the factory tolerances are not good! We are pretty confident it is in the right place and who knows it could be located better than it is from factory.
