RE: gear

mpsautosalvage has 3.73s for cheap, if you buy them new, id recomend 4.10s instead, do NOT try to install them yourself unless you have done it multipule times before on someone elses car

RE: gear

you will loose an additional 1 mpg if that with 4.10s

4.10s can be found at americanmuscle.com discount code is mustangboards
mpsautosalvage.com has the used 3.73s

RE: gear

You will lose top end speed. But how often will you ever need to go that fast? Both gears are fine I just prefer the 4.10's as well :]

RE: gear

And dont forget that you need gears for a 7.5 rear-end, not the 8.8 which is what the ones in that link were for.
