correct one. I recently installed a driv shaft from IPP and it was doing the same thing as you descibe. I pushed the yoke in as far as I could until I could no longer move it by hand. I then used a rubber mallet to tap on the end of the drive shaft and it went in without issue. I didn't beat it in, just hard enough to make it move and that didn't require a lot of force. I would not have thought it would have been as easy to drive it in with the mallet, because it wouldn't move pushing by hand. All I could figure was the the yoke didn't have as much of a beveled edge as the OEM shaft. Hope this works for you.
