I have a 94 Mustang GT Conv. What's the difference between the 28 and 31 Spline Differentials? I'm looking to have some drive train work done. Installing limited slip differential, new clutches and 3.73gears. I'm hearing grinding noise in the rear end when I come off the clutch and I have 20" rims on her. I read it was better to replace stock the gears anddifferential. If anyone has recommendations, please share. One more question, are the stock gears 8.8"?

RE: Difference between 28 and 31 Spline Differential
31 spline axles are stronger than 28 spline and you need a 31 spline diff to run the axles. I went with the '03 Cobra diff and moser axles for my setup, so far so good.
RE: Difference between 28 and 31 Spline Differential
Actually I'm fairly certain that the '94s onlycame with either 2.73s or 3.08s. For manual at least, I'm not too sure on autos. Feel free to correct me if I'm wrong though.
RE: Difference between 28 and 31 Spline Differential
do they not make upgraded strenght 28's?

TRADE MY Mach 1 HOOD + scoop set up for easy GT install (attached, no intake system necessary, unless you want it) for a COWL hood and maybe STOCK + CASH (but probably not). The hood is painted silver, in great shape, does need a color sand, but thats no biggie. Would prefer a swap for a silver one, but will consider many options. Need to trade due to changed plan on this car. RTP/Greensboro/Charlotte
