Outer Limits 4x4 Board

I have a gq front diff in my shed and am wanting to know if putting it in without a rear gq is a good idea ? can i match ratio's im currently running std setup with 35's this truck is being set up for winch challenge type events .Thank you in advance Stu....

Ah, weird setup. you can get 4.1 Rover diffs, but they seem to be pretty hard to get right at the moment.

The gq diff would be wider.
