Hi Gary,
By my calculations your overall ratio in 4th will be 4.1811,  a 2wd with .85
4th and 4.86 diff will give you 4.131.
The same ratio for all intents and purposes.
This is indeed a simpler and cheaper way than changing the diff ratio!(ANY
091 boxes are as rare as hens teeth in this part of the world).
My interest is I have a '82 transporter that was originally powered by a
1600cc air-cooled engine (avail in Europe, don't know about North America).
This also has a 5.43 diff  but 0.82 4th as stock.
I am in the process of putting in a 2.3 Audi engine, and have calculated at
118kph (68mph) the engine will be turning 4000rpm, a bit high for my liking.
I will investigate the different 4th ratio for the box I am rebuilding at
present. Maybe find a source in Australia, as at present exchange rates
parts from the US become veeeery expensive.
Thanks and regards for the info.
John.
