Need help identifying Steering Knuckle / Spindle

[David K.]

I have gone through the archives trying to gather information to positively identify if this is a 67 Steering Knuckle....but am still a little confused. The (2) Steering Knuckle holes

1. Should all (4) holes

1. Is this a Steering Knuckle #3864023, #3924384, or #3953416 ?

BTW the Steering Knuckle / Spindle has a cast mark (180A) + GM.

Thank you in advance for any input.....Dave 23277

Re: Need help identifying Steering Knuckle / Spindle

I have gone through the archives trying to gather information to positively identify if this is a 67 Steering Knuckle....but am still a little confused. The (2) Steering Knuckle holes that accommodate the 7/16” Steering Knuckle Arm bolts measure 1/2” in diameter. The diameter of the Spindle shaft is 1.25” (where the inner bearing would reside).

However, the (2) holes in my Steering Knuckle Arm, #3817594, are 7/16” diameter. This is why I’m questioning if this is a 67 Steering Knuckle.

1. Should all (4) holes in which the 7/16” Steering Knuckle Arm bolts pass, also measure 7/16”?

1. Is this a Steering Knuckle #3864023, #3924384, or #3953416 ?

1. I’m thinking it’s a 3924384 ?

BTW the Steering Knuckle / Spindle has a cast mark (180A) + GM.

It's a GM #3924384 (1968-only).

By the way, the 3924384 is quite hard-to-find. It was a one year only part and was exclusive to Corvette.

For 1968 owners, the 1969-82 spindle can be retrofitted if the 1969-82 hub and bearings are also used.
