Custom Mainspring Housing for Compact 1911????????

I want to replace the crappy plastic mainspring housing on my Kimber Ultra CDP with a custom stainless job. I do not want a checkered or smooth MH. I have seen some that are scalloped and some that have those little golf ball dimples. Anyone know who makes them? I have a call into Burns Custom Guns to see if he will make his "wave" cuts on a compact MH, but would like other suggestions.
