727 throttle pressure linkage

Does anyone here have a good source for purchasing reproduction or an original set of kickdown linkage for a 727? Right now I have the Bouchillon kickdown cable but I am looking to go back to the original 3 metal rod setup. It seems these are hard to find through the restoration companies and I was wondering if anybody has purchased one recently through someplace they would recommend. Thanks

mega parts. won't be cheap though but quality parts.

For what motor?

SB or B/RB 727 3 piece set ups?

what is wrong with the Bouchillon set up? do you have all correct pieces for it?

willing to trade for good used 3 piece set up?
