Kingpins

[Shoebox]

Did a search on this topic, read many posts.. much good info. I need to install kingpins in my 39 Merc, I do know that I will have the bushings honed to fit at local machine shop. What I would like to ask is there a better source than another for the actual parts? I know most of the major old car sources list kingpins but in this day of dubious parts quality, is there a BEST source for these parts? I have learned that is the case for wiring, dist. rebuilding, carb rebuilding, authentic hardware, etc. so,.........I welcome any input on the subject. I also welcome any general advise on the whole process....... I am 61 yrs old but have never "done" kingpins.

Thanks in advance for any input!
