For those of you following this post, I spent some time discussing the issue with Tom Kirkham. The present thought is that the differential is in fact to full. According to Tom, filling the diff to the bottom of the fill plug is incorrect and results in a level that is to high in the diff housing. Several of their cars have the lube level approximately 1" below the fill plug. He suggested that I refill the unit with the specified volume (the orginal Cobra manual specifies 3 US pints). This should put the lube level at approximately 1" below the filler plug and should solve the problem.

Tomorrow I will drain all the fluid out and refill with the correct volume (not to the filler plug.)

I'll post another update if this turns out to be the solution.
