As you noticed the steering doesn't quite work:
And the tires stick out:
There are ways around it but none are a direct fit. I'm adapting 1985 spindles and steering assembly to make it front steer. I also have wider fenders from a F-6 with dump axle and going to be making the frame from scratch as I want a better fit.
Honestly there are better ways to update the suspension like AX said. I'm just stubborn.
