To start, if you haven't already looked at the build's of my '56 and Lonnie's '55 we tried to document those as we put out cars together. Here are the links:
Another good resource is the April 1967 issue of Hot Rod magazine. It has a cool article about putting a straight axle on the front of a car. Hopefully I can scan that article and put it up here in the near future.
Info from Speedway Motors
OK, here are a couple of documents from Speedway Motors on straight axle installation and parts to get from Speedway. Now I'm not endorsing these, but thought that they might provide some useful information, use them at your own discretion.
