1953 Mercury Monterey Front suspension

[Eaglescout2457]

I am currently finishing up replacing the leaf springs on my car and will be starting the front suspension in the next week. I purchased the rebuild kit from shoebox central. does anybody have any tips or tricks for this process? I have done suspension work on newer vehicles but nothing that had the shafts as shown in the provided photo. Any tips with the kingpins would be appreciated as well. Thank you!
