1957 ford 600 Spindle

[cyril57]

I have a 1957 Ford 600 I won at an auction this past summer. It was in working order. I am in the middle of the restoration. I usually restore cars & motorcycles but I thought I would try something different.
In the Ford parts catalog there are different part #'s for the right & left spindles. 3105, 3106. Can anyone tell me what the difference is? Please don't tell me $20, I got that.
Thanks, Cyril

The position of the key way for the spindle arm is different.

Thanks Something so simple.

I also believe there is a small amount of caster built into the spindles to make it
steer better.
