93 front suspension questions

For the spinning shock rod (or are you talking about struts?): The shock should have two flatted sides to put a wrench on (to hold the rod while you break the nut loose).
If you mean the strut: PB the crap out of the nut. Then get a longish prybar (the kind that are like a long screwdriver but with a slight bend near the tip). Put the tip in the strut slot, with the prybar PARALLEL to the ground (this gives you leverage to keep the rod from spinning! If you try to orient the prybar like a normal screwdriver, your wrist will fall off before you can hold the rod from spinning).

I have poly all over the front end of the 88 GT vert (including the FLCA's). You should not have the issue you are. Are the bushings seated in the LCA bosses properly? I have read of people slightly spreading the ears in the K member but I have NEVER done it and would not know about it.

You are correct that about which method is how many of us do things (it's often called the MFE method). I no longer recommend doing it (though it's still how I do things) because people have struggled with it. It is often about the only way to do things *IF* you do not have the OTC spring compressor (you really might wanna see if you can find one of these).

Good luck.

This type would probably work very well if you swing the spindle out of the way first.

This is the type we used on my springs. It is not easy to get in or out of the springs when they are installed but it works.
