ok im new at posting pictures so please deal with me. the brake drums are 12 inches from outter fin to fin. 9.5 inches inner diameter. the have 40 ribs also. the axle is approx 52.5 in long with 41 inches between the radius rods. the spindle/ kingpin is about 2 3/8 inches tall. the radius rod holes are about 2 1/4 inches. the radius rods are aprox 46 inches from factory weld to axle. i found a number on the rasiuss rod i think it read 214341412? anyone have a clue cause im lost
Probably 21A 3414? Likely the number for the forging, which had a PN even though it was not sold separately from the wishbone. Whole wishbone would be 21A 3405, 21A indicating 1942 intro, used up through '48.
I was wondering if they were from a Buick too. I thOught Buick drums were aluminum and had less than 40 fins that's why I'm questioning. I found them on a 60s Chevy van and they've been redrilled for the Chevy bolt pattern.
Lots of rear drums were finned. The popular "buick finned drums" are aluminum. Whats the bolt pattern?
The traditional type Buick drums were big car parts with 12" inner diameter...9.5 finned iron were used on smaller cars in '60's and '70's before discs were standard, like a Nova front brake.
