M.B. DOC - mo' explanation please

I'll be needing to recalibrate a 107 chassis speedo soon as a result of taking it out of a car with a 2.47 rear end and putting it in one with a 3.07 rear end (24% difference).

1. How is recalibration done? Is it accomplished through substitution of different speedo gears, or substitution of different electronic chips, or twisting a screwdriver (adjustment)?

2. Is recalibration something someone with typewriter repair skills and some electronics knowledge could do with a good set of instructions, or only to be tackled by a well-equipped speedo shop?

Most places that do it say it will cost $100, so it can't take that long once you know what to do.
