I have a 1960 stock Bugeye. I have two manuals, but together I still don't have all the torque values I need. I have torque values (ft/lb) for the following pieces - are these correct?
steering arm nut: 39
trunion fulcrum pin nut:40

I need torque values for these parts:
Spring pan nut:
Fulcrum nut for wishbones:
King pin (swivel pin) nut:

Help with any or all of these is greatly appreciated.

After putting the driver side together, I understand why torque values are not given for some of the items I had questions about since it was a matter of lining up pins. All I guess I really need are two torque values: 1) spring pan and 2)lower fulcrum nuts. Anyone have these available?

spring pan is just tight - it's metal on metal.

don't see a value for the lower fulcrum nuts - sorry.
 
Spring Pan bolts are 5/16" and indeed metal to metal. 15 #-ft. is more than enough.

Fulcrum nut for wishbones. This is the two pins at the body attachment - right? These are shoulder bolts with the guitar shaped washer and bent locating tabs. Again about 15#-ft here too. The are in shear and only need retention.

King pin (swivel pin) nut. This can be castellated or nylock. Which ever, there are shims under the top piece that keep from crushing the oilite bronze washer. Make sure those are there and hand tighten until you get some tightness and back off if castellated to line up for the cotter pin. With nylock, tighten slowly to about 15#-ft as well and check for sufficient play with the shims. Zero preload is best, a few thousandths is okay. Noticable movement is not.
