Was such an axle ever made? The markings on the housing say 45 in all the usual dana spots. This axle has a six lug bolt pattern and the axles are held in with 4 bolts similar to a 9''. It has a powerlok diff and if I am reading the date right on the ring gear it was manufactured in '58. Ever seen an axle like this before? What was the application? Thanks for any info.
