This might be one of those stupid questions but I will ask it anyway? If I put a Ford 8.8 with 4.10 gears in the rear of my 89YJ and keep my DANA 30 front and install 4.11 am I going to have issues? Or are they close enough to matching that I will wont have problems.

Please don't everyone heckle me at once, take your turns.

89 YJ, 3.5" Black Diamond Lift, 33" tires, 8000lb Warn, 4.0 91 XY engine swap.
