#9 of 39 Chrome differential cover by joe110 Apr 08, 2006 (8:38 am)
I just installed a chrome diff cover. For anyone else who wants one, go to Jegs.com. The rear of choice should be a 8.8 10 bolt. There is no listing for a crown vic. You have to match it up as a mustang GT. Looks nice too. Paid 33.98 delivered.

Replying to: joe110 (Apr 08, 2006 8:38 am) It the rear diff cover just flat chrome, or is it cast with heat dispersing fins??? Replies to this message: joe110 (Apr 09, 2006 2:32 am) marsha7 (Apr 09, 2006 2:41 pm) p100 (Apr 09, 2006 8:25 pm)

Replying to: marsha7 (Apr 08, 2006 4:48 pm) Its just flat chrome. The ones you are talking about are like 180 bucks or so. Polished aluminum I think. Replies to this message: marsha7 (Apr 09, 2006 2:41 pm)

Replying to: marsha7 (Apr 08, 2006 4:48 pm) Keep in mind that aluminum dissipates heat three times faster than stamped sheet metal. Therefore, finned aluminum transmission pans and differential covers are the best.

#14 of 39 Back to dual exhaust..... by dekester Apr 14, 2006 (5:01 pm)
If I change my 03 to a dual system, would a crossover (or "H" pipe) help? I know this balances the sound and back pressure on other cars. Would I need to "flash" my computer? If so, where would I go to get this done?   Since I'm younger than the usual Grand Marquis owner demographic (at elast in Florida), I want to have mine stand out from the crowd a little. Looking at some aftermarket wheels; really like the American TorqueThrust "D"( with the dark painted spokes) or the TQ II which are all polished aluminum. A little pricey, so I'm considering the old standby - Cragar S/S, but I can't get anyone to tell me what size/backspacing/offset matches the stock steel rims so I can use the tires on the car now.   Upgrading to a set of factory LS alloys will run me about $200 per....   Deke Replies to this message: jsylvester (Apr 15, 2006 4:52 pm) dekester (Apr 16, 2006 3:41 pm) jsylvester (Apr 16, 2006 6:19 pm) p100 (Apr 17, 2006 12:38 pm) joe110 (Apr 16, 2006 4:43 am)

Replying to: dekester (Apr 14, 2006 5:01 pm) Get a set of black steelies, and put the chrome center cap, and maybe chrome trim rings. A lot cheaper than alloys, and looks "industrial" to me.

Replying to: dekester (Apr 14, 2006 5:01 pm) You should have dual cats already. Take it to a muffler shop or specialty shop and tell them you want true duals put on it. You can choose whatever kind of mufflers you want. Loud or soft. Or buy your own. As far as flashing the computer, some say the car will run rough when the duals are installed and the computer needs to be adjusted. Or some say the car will run fine. At any rate, flashing the computer will give you 12-25 more HP and increased drivability. Go to SCTFlash.com and go under "products" and click on "ford products." Or speak to the guy I dealt with and ask him anything. I bought my Excal2 from him. He knows his stuff. My 05 kicks butt now. And no, Im not working for him or anything. Im just amazed at what a difference it makes on the car. Go to dp-tuner.com. Just tell him what you want out of your engine. Good luck!

Replying to: jsylvester (Apr 15, 2006 4:52 pm) If I do that, it'll just look more like an unmarked SHeriff's cruiser. Mu GM is Aspen Green with dark tinted windows. I fool people sometimes when they look quick, but once they see the crome grille and rear end reflector, they realize is isn't what they thought it was.   Deke Replies to this message: jsylvester (Apr 16, 2006 6:19 pm) p100 (Apr 17, 2006 12:38 pm)

Replying to: dekester (Apr 16, 2006 3:41 pm) Got it. The problem you have is they changed the wheel offset for 2003, so you cannot use any wheels designed for a pre 2003 Grand Marquis; otherwise I'd suggest the lacy spoke wheels on the 95-02 HPP/LX Sport/LSE models.   They would be fairly easy to find used. New wheels will cost ya.
