I've got a 79 F-350 that i'm swapping in a 300 I6, I'm guessing that i have to swap out the engine perches that are bolted to the frame? where can i find those?

 

On a truck with a 300 in it.

The 400 and 300 have different bell housing patterns, so you'll also need to swap bell housings if you have a 4-speed, or entire transmissions if it's an auto.

 

yeah . . . I'm attempting a frame swap, putting my '53 F250 body on a 79 F350 frame. The 400 is too much for a daily driver so I'm building a 300 with an NP435. I've tried looking up the part but to no avail, If they are not too expensive I'd prefer to buy those new to avoid any surprises down the road.

This is all i can find, the mount that bolts to the motor
