Transmission swap issue

[JonC]

My 40 pickup came to me with a 4speed, I wanted to put in a 48 car 3 speed. I just primed the frame and looked at the trans mount, it seemed wide and yes it is the spacing on the truck rear mount is 2 inches wider than the car trans mt. They of course will not interchange, before I make some wierd mounting bracket is there a common way to address this. Thanks
