Anybody have a driveshaft yoke?

Hi all,

I've got a '73 Fury II with a 318, 904, and a 8.25 rear, I need to find the front driveshaft yoke. When my U-Joint blew, it tore the old yoke in two. I'm currently running a B-body yoke, and there is a vibration above seventy or so, because that unit is an inch or two shorter in the tailshaft of the trans. Any help would be greatly appreciated. Due to my airplane gears, that's sort of the car's sweet spot. Thanks again,

Matt
