W58 Gear ratio converter on speedo output? Why?

My mate just bought a W58 the manual 5 speed from an ma61 and it has a gear ratio converter actually attached to the gearbox, its only small.
Mine is manual, why doesn't mine have it? Both boxes came from cars that were originally manual.
Anyone have any ideas, or is it just for different diff ratios?

Sounds like your mate bought a gearbox that was put in a car with different diff ratio and/or wheel size (ie non-original box), so the converter was necessary to bring the speedo back into line.
My speedo reads about 10% fast because of this - I'm pretty sure my W58 originally came out of an MA70 Supra with a much taller diff ratio. It's definitely not the original box as the car was originally auto.

The ratio converter i saw on my mates gearbox, its about 3 inches long with a dog leg bend in it. It screws into the gearbox where the speedo goes in and the cable goes into the other end of it.
He says they exist on all the gearboxes both man and auto,

I've never seen one, and I've been under quite a few Supras! The speedo cable screws directly into the box in both of my MA61's (one manual and one auto).
