Help with quick change yoke

[RW57]

We have a car with a jones quick change rear end. I know parts from a winters or frankland will fit or so I am told. Here is our problem it has some kind of odd ball rear yoke and we are having a heck of a time trying to figure out what u joint will fit it. It takes a 3 1/8 wide u joint where every thing I find takes A 3 7/32 wide or nearly 3 1/4 wide joint it also appears to take 1 in dia cups everything I find or have the cups are to big . I have found a joint in my junk pile that fits the yoke but it is too small for any driveshat u can buy or I build plus I do not have a clue what it is my Dad thinks it is a Dodge. If we buy a replacement yoke what will fit it Frankland or Winters .We want to race next weekend but this has turned into a major roadblock I can borrow a drive shaft but because of the yoke it is a no go. We just want to standardize it so we can pick up parts without having to go though this again.

Here is a yoke from speedway. It should be direct replacement. We had an old Jones at one time too. The winters yoke uses a 3 7/32" by 1 1/16" ujoint.

As a matter of fact here it is:
