t-90 to gm adapter gasket?

I am still plugging away at my project and have come across another couple questions for experts. Is there supposed to be a gasket between the transmission (t-90) and the adapter, also is there one between the adapter and the bellhousing (GM)? and if so where does a guy go to get them, I tried the advanced adapters web site and didn't see what I was looking for. Thanks.

 

No gasket in either location as far as I know.

 

offy used one between the adapter and the trans case
there should be an oil seal in the GM type bearing retainer.

 

I did see the oil seal in the adapter, will replace it. But am considering making own gaskets to put in both locations don't think it will hurt anything.

 

Other than sealing any oil that leaks by to be sent to the bell-housing and on to the clutch. The T-90 input bearing retainer has a milled channel at it's flange to direct any oil leakage down and away (I thought).
