just picked up a set of 4.10s from jegs. Ford Racing M-4209-G410A - Ford Racing Ring and Pinion Sets at the ones i got. i remember someone telling me something about if theyre 31 spline i have to get a new differential. i counted 30. will these fit in my stock 03 gt differential?

They should. I've never heard switching to a different differential for a gear swap.
