[FC] Front suspension differences

[N2VZD at aol.com]

no need to change crossmember. just tank. i saved a few chunks of floor and 
 rest of linkage years ago (i have parted out a LOT of corvairs over the 
years!)  but sold them when i changed all of my stuff to powerglide.
important to get the upright portion of the late floor , or shifter WILL be 
 "wiggy". dont ask how i know , but it was a project to correct that 
problem. i  ended up bending a chunk of 1/4 inch plate to fit , cutting the 
shifter hole in  it , then brazing the l shaped piece in place. lots of under
coating covered it  up. what a difference!
the next one i did for myself was much better to do with the larger chunk  
of donor floor.
hope this helps...
i do not think there were any major changes in suspension  front or  rear 
over the years. i have a 61 i am parting out right this moment.
