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

[jasonxst]

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
