Master Cylinder Adapter

The thing is, I'm a picky SOB. Lol. It's gotta be aluminum not steel. Also, I want a radius on the outside corners and raw without any finish on it. I don't currently have, do to the lack of space for more tools, the means to fab one myself. I found a few places to get them. I just sent out a few emails to see if some of the guys can tweak their product for me. I'm also a cheap SOB. Being picky and cheap requires a lot of patience. I just wanted to see if someone here had one lying around that I could get on the cheap and make minor changes to if necessary. I'll let you know how it works out. Thanks for the responses and suggestions.
