Re: 1957 Chevy 3100, meet 1994 Dodge Ram 1500
Here is the resolution to the clearance issue between the front bumper and the transmission cooler. The perspective is off in the last two pictures. They were taken looking down at the cooler, not up.
The hole saw worked quite well and didn't booger up the chrome bumper. Since I was only cutting a notch, I clamped a piece of 2x6 to the inside of the bumper, sticking out past the edge I needed to trim. Then from the outside of the bumper, I started my cut. The pilot bit for the hole saw was drilled in to the wood block, right at the edge of the bumper, keeping the blade steady while it cut the metal. I used a little oil to help cool the blade while I cut.
