Gear Ratio Match Up

[Captainfab]

I'm helping a friend gather parts and install a 10 bolt front and 14 bolt rear under his Blazer. The 10 bolt front has 4.10 gears. The first 14 bolt we pulled has 3.73's so the search began for another with 4.10 gears. I found a early '80's G20 or G30 with a 14 bolt, but it has 4.09 gears. I had never heard of such gears for a 14 bolt, but in doing some research, it seems that is a common gear used in the G series vans. So my question is, has anyone used a 4.10 front gear with a 4.09 rear gear? I know that is backwards from the normal ratio match up, but I don't know how it will act with the rear wanting to push a little.
