It is a ton of work...did my very original '49 woodie recently.
Ref the king pins, I had a local shop install and ream the bushings. There are some thin 'washers' that are shims to reduce the play, you add these to the bearings.
The bushings that screw onto the cross shafts that came with my kit - not from Shoebox Central, Dennis Carpenter were crap, soft metal.
You would think Dennis Carpenter's company would have some quality products. Those days are long gone. The zerk fitting threads were metric. I cleaned the original zerk fittings and reused.
Those rubber seals are a real fun time to replace. You will long for the simplicity of ball joints.
I reused some of the fasteners, though most were replaced with new grade 8 hardware
with that funky chromate plating.
I replaced all the steering parts at the same time. Once completed, you will notice an improvement.
Looking back at the project, with all costs and time involved, the use of a modern IFS kit
from suppliers like Heidit's, et al, makes sense. I would not hesitate to install on a original car.
Have fun!
