3:70 gears in an 80 series?

[davegonz]

Akella on MUD can source the front hi-pinion 80 series 3.70 gears. I did that on my old 4BT powered 80 series. Another option is to regear the transfer case gears instead.

You may have already checked but are you absolutely sure you have 4.10s already? I mean idk for sure that I have 4.88 because I have never personally checked. It only takes 5 minutes to check. It would just suck to put in 3.7 gears when u had 4.56 in there or something lol.
