Thanks Manager,
I just was really confused. The only numbers I could come up with for the axle measurements was found on the HaMB searching Google. He said the axle was 51 1/2" in length so that was the first thing that through me off. The second part was speaking with a gentlemen who builds early fords. He was telling me that the 33/36 axles do not have a 2" perch boss. I took his word because I was at his shop looking at 8 different early fords he built. So with all that said the confusion is the main reason for the multiple posts.
Here's the main issue I'm concerned about and that's the width because of the spring perch arms that bend towards the backplate. With the SoCal axle being 1 1/2" shorter in length the backplate looks as if it will hit when turning.
