Mag-Hytec Differential Cover On 2002 Mustang GT?

Has anyone installed a Mag-Hytec differential cover on their 99-04 Mustang GT?

It looks like a really "high-tech" diff cover. It has a magnetic drain plug, magnetic dipstick (which I think you can use to fill it), it has an extra 2 quarts of capacity, extra cooling, a temp sender fitting, no sealant required, etcetera, for $250.

I was looking at a few websites:

http://www.drivetrain.com/differentialcover.html

According to the http://www.mag-hytec.com/differential covers.htm website, there is one which is for a Ford 10-bolt 8.8-inch rear end which "fits light duty F150, Ranger, Explorer and some vans".

But does it fit a late-model Mustang GT?

I just looked under there, and it looks like the Mag-Hytec might fit, except that there is a metal bar that sits about 3 inches behind the lower part of the diff cover. (Is this the "rear sway bar"?) Also, the top part of the Mag-Hytec might not fit, because of the bulge of the spare tire well, which is also about 3 inches away.

So maybe it won't quite fit.

I guess another option is the SVO, as mentioned by True Blue, which is in the Ford Racing Performance Parts 2002 magazine. At least that one seems to have a fill plug, as well as a drain plug, judging by the photo in the magazine. Is this true? Does it have a fill plug and drain plug?

I really like the idea of a fill plug, because the stock fill plug seems to be held in place with threadseal tape (or some sort of red gunk), and it's in a really awkward place (it's the plug on the driver's side, on the front part of The Pumpkin, with screw threads on the outside and a sort of hex hole on the inside, right?). Also, the stock fill plug looks a little low to me.

The only downside I see, for the SVO, is that it might have slightly less capacity, because it might not have that bulge that the stock diff cover has. Or does it? However, this may be offset if the fill plug is higher than the stock fill plug, meaning I can fill it higher(?).

Again, has anyone thought about using the Mag-Hytec, or actually installed it, on a 99-04 Mustang GT?

Or is there another diff cover/girdle that's better than the SVO diff cover?

Another one I see is in the Summit 2003 catalog, page 49, manufactured by Summit. It has a nice bulge (perhaps too large) in the back, but the drain plug looks like it's a lot lower than the one on the SVO diff cover.
