King Pins?
Well drivers side needs kings replaced. Should I use metal or nylon bushings?
Nylon is about 10 bucks more. I'll spend the money but what is better? Opinions, tips, and tricks are all welcome.

Metal all the way... Nylon (or whatever plastic polymer it is) starts to loosen up around 40K miles. Granted ya might not have the truck that long but a little effort now goes farther down the road.

Plastic bushings don't require reaming. The down side is they don't have near the service life of bronze bushings. Keep the kingpins greased and the bronze bushings will easily last 100,000 miles or more.
A local machine shop had loaned me the reamers (for free) for me to do my own bushings. I had never done this before but, it doesn't require being an Einstein to figure it out. I used a Moog kingpin set with .859" (55/64") pins and bronze bushings. Part number 8540B.
'77 F100 I-beams/discs I swapped onto my '69 F100.

I just did bronze bushings in the '73. I honed the bushings to size. That way you can sneak up on it and set vertical clearance down to the .001 of an inch. I set them at .003" (.006" bigger bore in the bushing than the diameter of the pin) Zero play in the front end.
