I have a yoke that needs go be replaced on my C20,,,,,it's the one that goes on right after the Carrier/Support Bearing,,,,,it has about 10 splines and is held on by a bolt in the center,,,,there's a number cast on to it #3740097.I wondered if they still make or reproduce this????

I was searching for a vendor that sells this center bearing position yoke but can't seem to find anyone that carries them. Anyone know if anyone is making and/or selling these?

Base on info I found the Dana Spicer 2-4-1921 is the same, but looks like most places don't have it in stock or say obsolete.

Here's more info on it.

Yes I was running into the same, no longer available. Mine has cracks where the c clips go in and I would like to find a new one but it may not be possible.

I think this is what your looking for ?

It's possible there is a difference between the C10 and the C20's. With all the folks converting to one piece drive lines there should be some good used ones around. Take a look in the classified ads.

Or better yet get your premium membership going and post a want to buy ad.

Thanks all for the input! I was hoping it would be something available new but it seems they are made of that special material unobtanium. I'll be looking for a good used one after I speak with the drive line shop, maybe they have a source? I installed the CPP rear slip drive shaft and poly center bearing and now I have a bad vibration so I think it needs to be balanced and when it is at the shop I'll have them try to cross reference the yoke.
