Re-gearing Dana 30

Ok quick question, Im getting a Chrysler 8.25 for my rear axle and re-gearing both axles to 4.56 gears. When I do the front Dana 30 do I need to get a new case or can I just change out the gears and it be good? This guy on ebay says I need a new case

unless you already have 3.73's (which you probably don't) then you will need a new case, just do a complete upgrade and get a Detroit tru trac in it!!!
