RSR oil cooler without rsr bumper?

[craigmakes3]

I just saw a picture of a 911sc that was built by tech9 in England(?) It looks as though they installed an oil cooler in the valance under the front bumper simply by cutting out a rectangular section of the valance. I like that look better than putting an rsr bumper on. Has anyone out there done this conversion? How is the cooler mounted onto the valance? What sort of mod's need to be made for the oil lines?

Thanks

I saw a C3 with slits formed/cut from the front valance, it looked
very nicely finished.

I saved this picture from this forum some time ago. It is similar to what you are describing. I think it looks sharp.
