Slant 6 727 Transmission

I have seen pictures of the iron adapters on the internet somewhere, but never in person. I restored a 61 w200 and wasnt aware of an automatic /6 option, maybe that was just on the 2wd models??

I have a 78 w100 with a slant and 727 in my boneyard, it is all aluminum- no adapter to the block and bolted to the 203 like normal.

Do you have any parts laying around for that 61? Some 1 year only stuff on those and very hard to find.
