Need someone with aluminum fab skills

[crays]

Is that a heel/toe shifter?

It looks as if it is a cast piece.

Trying to to mill some thing similar out of bar stock would be prohibitatively expensive. Buying the part would be cheaper.

If you have access to some (scrap) stock and the proper equipment, that's a pretty easy/cheap part to fab.

Finishing to match...Whole other issue.

ETA: the splines at the attach point will definitely add time and cost.
