I finally got the linkage worked out. By cutting and welding the bellcrank I was able to get the angles to match the bellcrank of the old motor. I welded at tab on the side of the throttle rod to attach the spring, then made a clip to anchor spring above the pan. Seems to work great and I won't need to modify the accelerator rod.
Take a look at my webshots page, in the 224 to 235 album to see photos of the motor and the modified linkage.
