7.25" to 8.25" driveshaft?

RedFish said
The difference between a 7.25 and 8.25 is about 1.5 ( I think the chart shows 1.25 to be exact ).
If nothing other than the rear was changed that's all you need to know. Take the OEM driveshaft to a shaft shop and have it shortened by 1.5

That's what I did when I switched from a 7.25 to 8.25. As RedFish says, I see about 1/4" more shiny metal than before.
