    after installing the ring and pinion, the set pin will not go thru the carrier hole to hold axles in place. it is like the ring gear is too thick, it only hits on one gear tooth but enough so pin will not go into place

    Asked by: sportcoupe
    Thank you for your question. A notched cross shaft is required for 3.73, 4.10, and 4.56 ratios for the Ford 7.5" differential. The notched cross shaft is part# 80-0271-1. The notched cross shaft needs to be installed before the ring gear is bolted to the carrier. The notched cross shaft section will allow you to install your c-clips on your axles.
