Where's a good shop to buy and have 4.56 gear installed in the DC Area?

Could you tell me if you got your 4.56 gears installed in the DC/MD/VA area and what shop is capable of doing it? Approximate price? I'd like to my 2004 SSR Indy Festival done. Thanks.
Okay, who wants to sell their 4.10's? I'm not ready to make the 4.56 jump yet.

If you;ve got a 6-speed, I can rationalize the 4.10 versus 4.56 for some situations. But, if you have the automatic, my computer modeling at the time I first proposed this "radical" idea of 4.56 gears to this SSR community, showed that the impact of the 4.56 on acceleration was so much greater than that of the 4.10 as to make the 4.10 a questionable choice.
Since the swap is not cheap ($600 to $900 in most markets, for parts and QUALIFIED labor), it does not make sense to do it twice.
The 4.56 gets an automatic up to only 2198 rpm at 60 mph in top gear, and imapcts fuel mielage very modestly. It makes the vehicle REALLY wake up.
To review reasons I have previosuly published as to why 4.56 is so good for an SSR:
1. The SSR has very large diameter tires - over 29" - much larger than on typical cars, so 4.56 on an SSR is like maybe a 3.3 or 3.5 on a Corvette or Mustang
2. The SSR is VERY heavy - MUCH heavier than almost any car and certainly far heavier than any performance car except maybe an original (large body)Impala SS. This very adversely affects acceleration, AND loads both the engine and the transmission very significantly at low rpm.
I think I have surely mentoned in earlier older posts that the computer modeling shows that the 4.56 gearing reduces 0 to 60 mph times, with a typical driver weight and half tank of fuel, by 3/4 second to 1 second. That's HUGE in terms of seat of the pants feel.

p.s. I would not recommend using anyone else's used 4.10 gears. The odds are that they would never be as quiet as they should be, as rear end gears must be precisely installed and they wear ratherr specifically once installed.

I was considering the 4.10's because of the speedo calibration issues and also mileage, although not a big concern (especially the way I drive). Doug Allen said he swapped his 4.56's out for 4.10's, but he didn't say why, I would like to know before I make a final decision. Maybe I need to PM him. Thanks again, by the way mine is an 05 automatic in bad boy black. I guess that alone is enough reason to go 4.56 and over to the dark side!!!!

He did because he has a supercharger and can't keep the tires glued to the ground. His is a 6 speed though.
My SSR: 2005 Aqua Blur #18290 born date:11-19-04 a rare Aqua-Blur six speed
How much?????????????????
OK, OK, OK!!!!!!!!!!!!! I gave in and said to Marv go and get those gears and you can have bragging rights. Just like the rest of the BOYS.!!!!!!!!!!! So the SSR is in the shop as of this Morning and the old 3.73 is out and the new 4.56 is going in tomorrow. He already has the 4.56 PERMAGRIN and just can't wait for the call to come and get it...
