Sorry if this has been covered before but the earlier posts I read had conflicting information.
I have a 261 out of a 1959-62 Canadian Pontiac that was equipped with a powerglide bolted to the 261 using a cast iron adapter.
Will any modern auto transmissions bolt up to the 261 using this adapter or is it just for the powerglide?
Thanks,
Bob
