looking for some seals

[Blue71Chevy]

start of with some specs
71 Chevy K-20 pickup
350 SB
Th350 trans np205 cast iron Tcase

im leaking trans fluid into the tcase i dropped the tcase and separated the adapter from the tcase i found a large round square edge seal on the adapter that mates to the trans and a small rubber oring on the tcase input shaft and a paper gasket between the adapter and the tcase. i need all 3 of these seals and im done wasting my time at local parts houses. if anyone has part numbers and somewhere i can order these from it would save me tons of time. and get my truck back on the road i have pictures of everything and can email them to anyone who wants to look at them. on a side note any recommended oils to refill the tcase with what i drained out of it was unrecognizable. Thanks!

well, i replaced the lip seals, could not find the o-rings or the gasket. used some heavy duty silicone for the gasket and reused the o-rings. during the process of cleaning the parts i found the adapter has a nasty crack that the previous owner covered up with black silicone. anyone have a spare TH350 to NP205 adapter? trans side has 4 bolts T-case side has 8 bolts. i have reassembled it, should be ok for what i need it for now which is daily transportation, i will want to replace it before i go offroad.

You may want to look in the classified section for that adapter.
