Ok, i will try to not ramble and get right to the question at hand here. 03 cobra with a 8.8 rear already has 3.73s in it. There seems to be a annoying squeak ( sounds like brake pads) and im not sure where its coming from. That and theres a bit of a clunk when going into first from reverse or a stop. Im lookin to just redo everything for future mods. On american muscle im looking at moser 31 spine axle w/ bearing and gasket kit, also the ford racing tloc with 31 spline input. Im wondering what some of you all think of my intentions and if anyone has a better idea. I hoping to get rid of the clunk and squeak by doing this as well. Im looking to do thi correctly the first time, plans for 500 to 600 bhp.....eventually. As of now theres 430bhp and 460 lbft.
