throttle body butterfly

Does anybody have a cad file or info on the butterfly plate used in bored throttle bodies? I want to bore mine out ot 62, and I need a new plate, but I want it to fit perfect! If i had a cad file I could just cnc it at work. I know there are angles ground on the sides to fit tight as well. It this something that can be fit in at assembly? Info would be great. Thanks a ton!

I think that a TB butterfly plate is available from someone like MORE or somthing like that for 10.00
if you cant find a CAD file - you might look into that...

My machinist just got me a butterfly last night for mine that fits like a glove, I'm sure he can whip you up one for super cheap.

he said about $10 would get you one.
