Like Rob said "Bolt it in"
Unbolt the 57's let it drop to the ground clean the frame up and slide the 75 IFS under your frame, measure and remeasure, drill the holes and "bolt it in"
Check out Robs truck
Here's a link to Steve Andereggen's site ( he's a fellow bolter) AND it's the very one that Rob installed in his 1950 3600.
With your frames both being the same width it sound's like it would be easier and a real clean install ?
Be sure to post some pictures ! I think using the 57 as your daily driver is awesome !!

Some people are like Slinkies, Their not really good for nothing... But they still bring a smile to your face when you push them down the stairs.
