trans mount help! cast iron to 727

So I have a 61 dart, the big one, and swapped out the cast iron trans for a 727, problem is I need a trans rear mount, does anyone know if a stock mount will work or is there an aftermarket??

Make some measurements on both, probably not a bolt in
I've own both but never tried to swap one from a early car to a later or vise a versa.
What are you going to do about the shifter if it is going to a 1962 to 1965 push button shift cable tranny ?

Year of the 727 matters, mount pad location changed.
