differential question, part #

[frapjap]

I went to the Nissan Dealership to buy some output flanges to my 300zx vlsd differential today, but he didn't understand that I wanted output flanges that would be compatible with the internals of the lsd, but still have the bolt pattern to match the 240's axles. (as most know, you need to change them so that the bolt pattern is correct; 2x3 and not the 5 bolt the 300z diff comes with) Does anyone have access to the part number for this, or at least a better way to describe it to him? I know its out there, I just am having a hell of a time to get it.
