A 7290 yoke is available for the 904's thru the aftermarket, I don't think the factory ever made one unless it would be for a truck/van application, but I don't think they ever did. Light travels faster than the speed of sound,,,this is why some people seem bright untill you hear them speak.

Never saw one if they did. course 904's in trucks or vans were virtually a non existent thing around here

It fits in the 904 but we cannot press the caps together far enough to get both clips in. I measured the space between the ears on the yoke and it is 1.125" It does not look damaged by looking or measuring. It just seems that there needs to be about another 1/16" between the ears. I have assembled plenty of u-joints and never had this problem so I am wondering if there was a change in that dimension for different years. ‘72 Charger, 5.9 Magnum, Tremec 5 spd., Pro-Touring ‘14 Big Horn, Quad Cab, 4x4, 1500

I have seen them semi air lock making them bit of a job to squeeze down to get the clips on and taking a couple of good raps with a hammer to get them to seat. Too much grease in the cups will definitely stop the seating possess till some is taken out.
