Anyone have a 8 1/4 sure grip with 2.71 ratio?

I'm not sure if the sure grip I purchased will fit my carrier which has a 2.71 ring and pinion. There are two different sizes from what I have read. Thank you.

I had a Volare 8 1/4 rear with 2,76 suregrip, I changed 3,55 gears in it. With 2,45 gears, center is different.

It doesn't really matter, but I wonder if the ratio available was 2.71 or 2.76 or both?
