TH350 Slip Yoke Question for '64

[MonteAZBB70]

We pulled the old 292 and 3-speed out of my Dad's '64 Suburban and replaced it with a worn but still good running 350/TH350 combo. We need to get the drivshaft shortened/balanced and replace the yoke for the tranny. This build is on a pretty serious budget, so I'm hoping to find a yoke at a recking yard or something that will work vs. paying $55 for a new one. I know, I'm cheap, but pennies count these days. Can anyone tell me what yoke would work? The old one was a 16 spline and the one needed is 27 spline. I'm assuming we'll need one that took the same style u-joint, right? Can I just use one from a newer truck? Any particular makes/models I should consider? Any thoughts would be apreciated!
