ford spring bushing question

[big83chevy4x4]

does anyone know what size bushings the 78 f150 springs use? shackle?

2wd or 4x4? I don't know the size of the bushings, but I believe the 2wd springs are 2.5" wide and the 4x4 springs are 3" wide.

im not sure, i had a chance of buying a set of poly bushings for a 73-79 f150 with a 3" spring for $10. just wondering in i can get something with the correct ID to put the bushings in.
