Hey mel, thanks for the pic, I appreciate it.
If possible, if the floor hole is still accessible, could you lay a ruler or tape measure next to the hole, with the ruler's starting "0" end at the floor crease just ahead of the hole, and take another pic for hole size and location? This would help me in prepping for my car's "surgery".
Do you (or anyone) know if this looks like a hole that was cut at the factory?
Thanks again!
