If it were me i'd go with a butterfly scoop, throw away the elements and hook the linkage 1 to 1 on the buterflys.
RPC is the source for these and can be bought for about $150.00 plus shipping if you have a source which i can hook you up with.
Here's the pics. of their scoops. Of course they have a million other pretty good items also, if you have adobi reader you can look at their cattalog.
