What kind of spindles?

[Reiner]

Hi Community,

i have a 68 C10 Shortbox and i want to drop it. I contact earlyclassic to order a 4/6 drop kit, but i have a little problem. A previos owner modfied my truck with disc brakes, and nobody knows, what kind of spindles he uses.

They are no drop spindles and they look like original GM, but i dont know what year and model.
There are some numbers at the left spindle: LH 68868461, 12846 7880, 461GM6N

Maybe you can help a poor guy from little germany? :-)

Thanks Reiner....
