Driveshaft support slop

[farside847]

After getting some good advise from some members on here, I rolled under my truck last night to try to wiggle my driveshaft (hehehe). The UJoints felt good and tight, with no slop at all. But since I have a 2 piece driveshaft there is a center support piece that has about 1/4" play all the way arround. Am I safe to assume that it should be tight and not be able to wobble?

So, I am thinging it needs replaceing and while Im at it I should probably do the UJoints for good measure. I looked it up in my 71 service manual and it mentions the use of a heavy press or vise. Can this be done with normal tools and not a press? I thought the joints were held in by little springs... Any advise on how to replace these parts would be much appreciated.

I looked up the parts I need in the LMC catalog and it confused me. There looks to be two versions of this center support piece? I think mine looks like part number 34-1671 (hey, maybe the 71 in the part number should tell me something since its a 71 c10)

Here is a pic of what Im looking at.
