It will make a difference on the A.P. springs. They have stock leignth, and 9" longer.
FOR THE REAR:If you have the longer springs then you should have moved the front perch forward around 6", sence it's an '87, the shackle mount should be moved back around 3".
9"shackles do seem a bit much, but what ever you do, tack weild everything and have 2 friends slowely put their weight on it and watch the movement, see how to change it for the better.
It took me 2 attempts at mine before It worked the way I wanted....Sorry I don't have picts....
