Back in my day it was a mustang II swap in 53 - 56 Ford pickups
Recently I saw that Crown Vic front clips are an easy swap in.
Basically 4 tubes cut into the OEM frame in the right places and the entire clip bolts right in.
In the 90s I took a 70s LTD front clip and built a frame off of that for my 56 F100
