I put a '77 front end in my '53.
The 53's stock track width is 59 3/4 inches. The 77 front end is 69. So I took out roughly ten inches from the crossmember and tacked it back together.
Now the bracket that the upper control arms bolt to is way to close together to fit in the frame. So we notched the frame in maybe 3-4 inches on either rail. Trimmed the tops off the main crossmember so it would drop down in the frame as far as possible.
Now the engine is a real tight fit between the rails. Reversed the stock 350 mounts. Bought some summit headers that looked like they may go straight out far enough over the upper control mount. More modification to the frame there aswell.
Now have a power rack from a mustang II to mount and then bring the steering over it all.
So you can do it, and do it cheap, you can make it work with the right width but manomano is it alot of work.
Good Luck.
