Driveshaft yolk

Hey guys. I have a 78 short box with a 5.3 and 4l60e. The donor truck was 4wd and the 2wd trans I got didn't have a yolk. All my parts stores around here can't source a yolk without the old one for specs. Does anyone know a part number to cross reference or a different trans yolk that fits into the 2wd tail? Thanks

Re: Driveshaft yolk

I was thinking the yokes were the same for t350/700r4 and 4l60e..

Look at summit pn u1661

Re: Driveshaft yolk

Stopped by a rotting squarebody in a field I knew of, the owner gave me the driveshaft for free! Sweet deal. The yolk from the th350 works perfect, thanks for the replies all.
