I'm looking at swapping this into my 02 5sp GT and I'll be honest - I don't know much about rear ends so I will be having a shop do the install. What I'd like help with is if this is all I need for the install for the shop? Also, looking for help to adjust my speedometer without a tuner. Sorry for the n00b post

Gear fluid (75-140, 3qt.) for the diff, friction modifier, gasket - check out lubelocker, an ecu flash for the gear ratio.

Yes that is a complete gear change kit. If you don't have SCT or HP Tuners to do your own tuning, You can pick-up a Ford Racing speedo corrector.
