The 3:55 year swap is a project you can do over a weekend. IF you aquire the bearings, bushing, and seals. When I did my rear end I also was given tools like carrier wrenches. These simple tools made the job that much easier. I used MT’s rationale when deciding what to do. In my case, I replaced the gears when I had it apart due to a pinion bearing failure.
I too have a copy of Patrick’s instructions. Same poor copy quality.
