64 Dart GT Slant 6 Convert to 4 speed manual

When the listing the listing says “alm” does that mean aluminum? If so, then it’s for the Overdrive transmission. The original 64-66 bellhousing is cast iron. I can take a pic of the parts number on my 65 bell when I get home later today. IIRC @Bigboy 68 has at least 1 64 bellhousing that was for sale.
Don thanks for mentioning me my last 64 Bell housing went to Brewer’s and exchange for credit on the 66 bell housing that I needed thank you I appreciate you always thinking of me
