i just figured that i would post a pic of the stock open differential for the 7.5
the T-lok looks almost like it. notice there is very little iron to support the spyders (which are missing in the pic)
now compare it to the pic of the Detroit Truetrac.
here is the pic

here is the pic of the detroit

the pic of the detroit is actually not accurate as you cannot see the helical gears at all. it is a cross section to show the gears in place
7.5 weakness eliminated

But I think you did good with the 03 Cobra.. I saw one yetserday that had a very insane exhaust setup... Sounded awsome and loud as he applied the gas...
