slip yoke late model

I believe it should be the same diameter as a 727, but the pitch of the splines is different. If you can figure out what year the van was that will narrow down what xmsn it is. Good sign that it had a 5.9 in it. Will research tonight to see if I can get the dimensions. If it is a 46 yoke, I will take it. You wouldn't happen to have the cooler lines for that van would you?
