Driveshaft support bearing orientation

[53charlie]

Hi all,
i am replacing the support bearing on my 1987 longbed. I have pressed the old one out but i am wondering if it was pressed in backwards? the support bearing is not symetrical, there is a front and a back, and there is also a small spacer, which i want to verify if it is pressed ahead of the bearing or behind it?. I have not been able to find a diagram that shows the orientation of those parts, anybody out there can help?

If there is any dirt on the cross-member that might help the orientation. Also, I hope you marked your drivelines so they line up together as well. The driveline is balance, so if you mount one 180* out of the other you will have a vibration.

Thank you for your reply dvdswan, the reason I have the driveshaft out is that I changed to a 700R4 trans (i had a TH400 before), so I had to look for a driveshaft front section from a truck that came equipped with the OD trans (3" longer), i found it, the U-joint is perfect but the carrier bearing was shot. So i will be using the original rear driveshaft section with the purchased front, hopefully it will work!
