Its been awhile since I have been on here.

I have a 93 Z28, I'm looking to put 373s in. I have a 2 series carrier with 273s currently.

I have been looking into Motive. I heard they have 2 types of gears.

"orange box" G875373X
"blue box" GM75373X

I have heard that I want the blue box cause they are much quieter. But, I can't seem to find the "blue box" ones ANYWHERE.

Suggestions? Links? Sponsors?

Thanks!!
