Rear susspension rebuild

[gmebey]

Now that I'm nearing the end of rebuilding the front end, I'm preparing to start into the rear. With that I'm in search of advice.

My truck is a stock 1969 C20 with coil springs and the Eaton H052 rear end.

Sorry for the long list of questions, but after experiencing the challenges with the front I'm trying to be more prepared.

1) What bushings should I plan to change and how many are there? I think 4, two in the lead of the trailing arms and two in the cross link?

2) What is a good source for the bushings?

3) What is the real name for the cross link? I'm can't find any bushings and think I'm searching using the wrong name for it.

4) Does anyone know the NAPA part numbers for the big u-bolts?

5) The big one. I think my trailing arms are in good shape with the exception of the top reinforcement plate is lifted on one. Is it advised to clean it up and weld it back down or use bolts.

6) Please share anything I may have over looked.
