Since this thread has gone from rear end gearing to OD transmissions, I'll confuse it with a lockup question. For those running A500's, what converter do you run? Do you defeat the lockup? I have an A999 lockup that I intend to put a GV behind once the wallet recovers from the current project.

The best I could find was a tweaked Dakota R/T converter. I've had it flash to 2500 (though my tach accuracy is suspect) but I'd like to be in the 2800 range. I have not been able to find an aftermarket lockup front cover for 904. Anyone know of a 904 lockup front converter cover?
