Thanks to all whom replied . Unfortunately did not really get a definitive answer . On the tool mentioned P/N MMT-8 , the supplier states will not work on stock springs . Have a copy of the Service manual & really could not find a step by step installation instruction . Phoned our local Ford dealer to ask about using their manual identified tool , no luck . So , here's what transpired , before it's posted , I'll say it , yes it is a bit of a "hackers " method . Had a set of cheap coil spring compressors which helped me to install my previously installed lowering springs . Installed "A" frame to the car with the 2 bolts . Installed upper insulator to factory coil , installed lower insulator approx. .5" from end as per manual instructions . Visually lined up coil with end being between hole A & B as per manual . Located my aforementioned spring compressors ( one each side of coil ) where I thought they would be easiest to remove . Tightened them up evenly until I could get the coil into the top location & partially on the bottom location . Was now able to get my hydraulic floor jack under the outer edge of the A frame & jacked it up a little till the coil looked seated on the A frame . Here's the bad ! Had to remove the compressors , the one facing the front of the car was no problem , just unscrewed it , the second one however , the hex for loosening was basically jammed to the A frame . Now what , even taking it all apart again , would not get any closer to an install than now ! Plugged in my air compressor , set up my high speed air grinder with a cutting wheel & cut the spring compressor bolt allowing the removal of the coil compressor in 2 pieces . Guess I'll have to go purchase another set of compressors to do the opposite side . Jacked it up till I was able to put the ball joint nut on . one question , using Ford ball joint which come with a nut with red loctite on the threads , how do you stop the ball joint from turning in the body whilst tightening the nut ?
