Drilling a couple holes went well. I was nervous to drill into 1/4" steel without a drill press, but the bit catching only broke my wrist a couple of times.
Now the crossmember has to cut and pasted/welded to fit my frame.
The only reason I even get to work on the car today is that plastic resin glue needs a good 24 hours to set to hold a curve. In cars, you can never have too much horsepower. In woodworking, you can never have too many clamps. Oops, I see a spot near the bottom where I can still fit another clamp. Gotta go.
