Gasket or seal between trans and transfer case?

[sp543]

I'm about to install marlin dual cases into my 85 4runner and am gathering all the parts before hand and want to make sure I have everything I need. Is there a seal or gasket that goes between transmission and the reduction housing of the transfer case? If so, could I get a link or napa part # if anyone knows it? I think there's supposed to be oil in the part of the case, but can't find a gasket that would fit.
Thanks

Yes we do carry that gasket, what's called a margasket. Give us a ring or pm Monday morning and we can get it done for ya!

Im also in need of the 8 stock crossmember bolts and one of the bolts for the transfer case mount along with that gasket, have any of them in stock or know what size they are?
Thanks
