sbc tranny mount question

i am trying to find a factory style ****** mount for my 59 chevy does anyone know if the ****** mount is basically the same from any 60's gm car

 

Looks like it's the same from 1958 to 1972. Here is a link that includes a chart:

It says TH400 but TH350/aluminum PG will be the same dimensionally.

 

Not quite Frank..
The t 400 has a wider bolt spacing than the t350 , pg etc.
Some aftermarket mfg's have gone to a slot in order to consolidate part #s.
