Can somebody offer up a bit of advice on installing the R hinges I got? Installing them to the body of the car is the easy part. What concerns me is how they attach to the engine lid. It's not exactly flat steel (or glass) in the area where the three screws and nuts per hinge go. I've got a steel engine lid and a ducktail. My intention is to use the steel lid. As best as I can tell I should probably cut out the underside, raised area and perhaps mig weld in some flat sheet metal there.

I could really use a couple pictures up close and personal of how the hinges are installed on the backside of the engine lid. Steel or glass, there appears to be a raised area between the outer skin of the lid and the underneath side. I suspect I'm on the right path with the cut and weld thing but could sure use some advice before I go into surgery.

Thanks in advance.....
