Looking for a rear main seal gasket

[DSMxTSi]

I need the gasket for the cap that holds the rear main seal. Anyone possibly have one laying around that I could buy?? I was hoping to get this tranny back up in the car this weekend, but now it's looking doubtful since Mitsu didn't give me that gasket when I was there earlier today and bought everything else associated with it. :(

Thanks,

It appears that Mitsu used silicone/ rv sealant instead of a gasket for the 7 bolt blocks. Has anyone done this on 6 bolts?? I feel fairly confident in using some silicone, but I'd much rather be sure before the tranny goes back up! :)
