Building an AV8 for what seems like forever but today I finally got around to filling an empty 78 top loader case with all the internals from a 46 48 side shift case. I purchased both Tardell's "Let me help you book" on this matter as well as Mac Van Pelts book that details this as well. I can't tell you how good these books are as they take you step by step with great pictures to guide you along. It made the process easy. The whole thing took about an hour to do. Thank you Vern and Mac as these are great tools for the rebuilder/hot rodder and worth the money.
