Exactly what I am trying to do.
I feel for you! Mind you, I'm donna roll the Big Six Oh at my next Nativity, but as a LONG SUFFERING junky and engineer, I can relate to your predicament well. (Most of my former associates were of your generation or older....) Anyway, screw the zip ties. They break after you go through the AGONY of compressing those damned shocks.
Here's The Morris Method:
Find a large screwdriver with a good handle. Doesn't matter what tip it has, you want shaft and handle.
Get a couple feet of rebar or bailing wire. Place the BOTTOM washer and bushing on the shaft and press them to their spot. Now, twist one end of your bailing wire around the shaft, over the bushing in a loop around the shaft, leaving ample length on both sides of the loop to reach the bottom eyelet of the shock, plus a good 6 or 8 inches. I like to double the wire to make sure it doesn't break. Stuff's cheaper than plastic zips too, Use it freely.
Put your screwdriver through the lower eyelet. Find some brick, or wood block with a hole in it large enough for the top shaft but small enough to stop the bushing you wired down. Grasp the handle one one side of the eyelet, and the shaft on the other, and USE YOUR WEIGHT TO PUSH THAT DAMNED SHOCK DOWN TO MINIMUM LENGTH! See, BRAIN, NOT MUSCLE!
Here's the tricky bit.
Now, thread each end of the wire through the eyelet from opposite sides, then twist them together. NOW you've confined the shock at its minimum length, maximum compression! You're ready to put it in your front end.
Put the shock up the tower, and get the shaft started into the top hole it goes into. Make sure your eyelet is at least close to where you want it in the lower control arm. Go ahead and put the top bushing on now, and the washer, and LOOSELY START THE NUT OVER THE END. You'll want room.
With the eyelet aligned to where it will go, now CUT THE WIRE. I recommend using good side-cutters with a sharp end, so you can nip the wires apart. You might do this one wire at a time if you doubled it.
God-willing, I'll make a video of this procedure for you and other Moparians in another month or 2, when I replace the front shocks on Gertrude. I MUST FINISH THIS COOLING JACKET CLEANOUT AND HEAD GASKET REPLACEMENT FIRST though.
Let me know how you make out with this. It's really easier than it reads. Rebar wire goes for $4-6 a roll too. Forget the worthless zip ties for this.
