Looking for a pedal rod extension

[Malamute]

Installing the MC and booster and the one in the old booster is not the same for current booster. It has male threads coming out and I need a female threaded clevis that is about 4" long.

I've found a few but they are all twice as long as I need or just the clevis which is too short. Any thoughts on where I can find something? Needs to be just a bit longer than this one.
