pinion bearing question

[1990MustangLX50]

I have a 3.55 ring and pinion out of a 87 Turbocoupe. Are the bearings for the pinion inner and outer bearing the same size?

As long as it was an 8.8 rear it should be. I can't remember what the TB coupe was. Using used rear-end gears is a hit or miss operation. Good luck!
