4.10 GEARS & EVERYTHING I need for the best possible install on 99 AUTOMATIC GT VERT?
 

I own a 99 GT Automatic Vert (aprox 55,000 miles)

Can you help me figure out EVERYTHING
I need to buy to have the GEAR job done right.
I am planning on going to a shop and having a pro do the install.


From reading all the posts I think 4.10's are my best option.

Is http://www.gefracing.com/
the best place to buy them?
It looks like 4.10's are $139.95


gefracing.com also sells all of the below,
which of these would I need???????:

1) Add Ford Racing Friction Modifier - a must for every new ring & pinion install. Only $3.35!

2) Electronic Ratio Adapter - a must for all 98+ Mustangs to have correct speedo readings. Only $133.00.

3) Add a complete pinion bearing kit for only $75.63.

4) Add a complete rear end bearing kit for only $162.49. Includes the complete pinion kit above plus axle bearings, axle seals and differential clutches. A must for higher mileage vehicles.



This is where I get a bit lost,
I know I need some type of chip for speedo correction
which ones would you suggest(I have no other mods)?
any clue where I can pick 1 up at a good price?


People also mention getting some of these items when
installing gears, do i need any of the following
(beyond the stuff I mentioned before at www.gefracing.com)???


aluminum driveshafts?
shift kits?
shims?
crush sleeve?
2.25 qts gear oil?
If so where can I order them at the best price??


I just want to get everything I need, have it
done at a good shop in Columbus, Ohio and
get all the parts and labor at a decent price.


Thanks everyone for your input & HELP!



PS
If anyone knows of any good shops in Columbus, OH
please let me know?

All you need is the gears,crush collar and pinion nut, Friction modifier,gear oil and the speedo calibrator. Try dallas Mustang for the speedo calibrator or the ratio adapter you mentioned sounds like a good price. However, I would suggest getting the complete bearing kit if you can afford it. Why not do all the work now and know it's all good. GEF racing is about the cheapest place for gears and related items.

I would highly recommend replacing the pinion bearing when you do a gear swap as it commonly gets damaged getting pressed off the old pinion and onto the new one and will cause you to have to get the whole thing done again.
I just had 4.10s installed in my '00 recently and this is what I got for the install:
- Ford Racing 4.10 gears. $129 from GEFRacing
- Ratech RAT-305SVO (for Ford gears; get -305K for non-Ford gears) install kit - includes pinion and carrier bearings, shims, crush sleeve, pinion seal and nut, ring gear bolts and cover gasket. $89.95 from Summit
- Ford Racing friction Modifier. $3.35 from GEFRacing
- 2 quarts gear oil. Ford recommends 80W90. I used Mobil 1 synthetic 75W90

-The SpeedCal will not work on 99+ autos, so you need an aftermarket chip or to have you computer reflashed.
