Cutting the floor should not have to happen. I broke a couple of shock bolts and knocked out the weldnut leaving a perfect hole to slide a 3/16" bolt taped to a box end wrench through the opening above. So simple, had both shocks installed with ss hardware in about 5 minutes.
I don't think Edelbrock makes the RE Monotube. It may be Bilstein. Not sure of the valving of the Edelbrock, but they were on my brothers Toyota and he changed them out because they were very stiff.
