Nice man glad it all somewhat worked out in the end. Any update on the inspection company?
As for coil packs stay away from red and yellow ones. Black (oem) or blue splitfires, or upgrade the whole lot to 35 GTRs/other new ones.
Usually the lower mount has a thicker/wider side, see image of the right side of the lower shock mount.
Don't see why a couple of washers wouldn't do the same job.
