Are 1986/87-93 4cyl K-members/A-arms shorter.......????

the control arms are the same length. the k member is the same with but the control arm mounting holes are in slightly, like half an inch. I have an 84 an i've been researching this because i'm doing a five lug conv on it in the spring. i picked up some 99 up control arms since they are longer so the tires wont tilt out on top.

The 85-86 Mustangs 5.0L used the same K-frame as the 87-93 4cyl. The only difference I noticed is that the upper spring perch has a big hole in the middle. the 5.0L is solid making it more rigid I guess. I have a 5.0L in my 91 with a 4cyl K-frame and A-arms, 94 spindles and it looks and works great.
