Just showing you the holes in the pan while the pan is laying on the table. Some of these holes are going to look a little oblong, don't worry about it.
Just a little safety tip here. I mentioned before I used cheap cotton gloves, take some duct tape and wrap it over the top of them.
I don't know if you can see it, but there is one good slice in that duct tape. These cut off wheels will get you...oh, I'm right handed, and taped the left glove. Also in this picture you can see the cut off wheel and the Milwaukee type grinder.
Here's a close up of a metabo cut off wheel, it's a 6"x.040 thick x 7/8" inside hole. They're good for 10,200 RPM. These wheels really work good for grinding welds, especially on the outside where the floor support attaches to the rocker panel, and on the inner wheel wells. They will reach in there where a regular cut off wheel won't. I had to take a couple of days off or I would have had more stuff on here for you.
