on the 3:73 gears i want to put in, where is a good place to get the 7.5 ....3:73 and all the shims and stuff you need to change the gear? also should i change my mass air when putting a cold air intake on?

You should get yourself a master bearing/install kit when you order the ring and pinion. Summit Racing or Jegs will have it all. No reason to replace the MAF sensor unless you suspect it's failing.

+1 Stl...... I would also go with a t-lock from either Ford racing @200.00 or so, or a detroit trutrac for @375.00 or so while you have the rear end apart. 3:73's will help you, but your car will sit and spin unless you lock it......
